1. A train 120 m long is running at a uniform speed of 36 km/hr. How much time will it take to cross a pole?

Solution:

Given that a train 120 m long is running at a uniform speed of 36 km/hr.
So, from the given data, speed = 36 km/hr, and the length of the train is 120m.
The speed of the train = 36 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
36 km/hr × 5/18 = 10 m/sec.
Now, find the time taken by the train to cross a pole.
Time taken by the train to cross a pole = length of train/speed of the train.
Time taken by the train to cross a pole = 120m/10 m/sec = 12 sec.

The train takes 12 seconds to cross the pole.

2. Find the time taken by a train 800 m long, running at a speed of 72 km/hr in crossing the pole.

Solution:

Given that the time taken by a train 800 m long, running at a speed of 72 km/hr in crossing the pole.
So, from the given data, speed = 72 km/hr, and the length of the train is 800 m long.
The speed of the train = 72 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
72 km/hr × 5/18 = 20 m/sec.
Now, find the time taken by the train to cross a pole.
Time taken by the train to cross a pole = length of train/speed of the train.
Time taken by the train to cross a pole = 800m/20 m/sec = 4 sec.

The train takes 4 seconds to cross the pole.

3. A train is running at a speed of 90 km/hr. It crosses a tower in 16 seconds. Find the length of the train.

Solution:

Given that a train is running at a speed of 90 km/hr. It crosses a tower in 16 seconds.
So, from the given data, speed = 90 km/hr, and time is taken by a train is 16 seconds.
The speed of the train = 90 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
90 km/hr × 5/18 = 25 m/sec.
Now, find the Length of the train.
Length of the train = speed × time
Length of the train = 25 m/sec × 16 sec
The Length of the train = 400 m

The Length of the train is 400 m that crosses a tower in 16 seconds.

4. A train is running at a speed of 63 km/hr. if it crosses a pole in just 14 seconds, what is the length of the train?

Solution:

Given that a train is running at a speed of 63 km/hr. if it crosses a pole in just 14 seconds.
So, from the given data, speed = 63 km/hr, and the time taken by a train is 14 seconds.
The speed of the train = 63 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
63 km/hr × 5/18 = 17.5 m/sec.
Now, find the Length of the train.
Length of the train = speed × time
Length of the train = 17.5 m/sec × 14 sec
The Length of the train = 245 m

The Length of the train is 245 m that crosses a pole in 14 seconds.

5. A train 60 m long is running at a speed of 36 km/hr. How much time will it take to cross a man standing on the platform?

Solution:

Given that a train 60 m long is running at a speed of 36 km/hr.
So, from the given data, speed = 36 km/hr, and the length of the train is 60 m.
The speed of the train = 36 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
36 km/hr × 5/18 = 10 m/sec.
Now, find the time taken by the train to cross a man standing on the platform.
Time taken by the train to cross a man standing on the platform = length of train/speed of the train.
Time taken by the train to cross a man standing on the platform = 60m/10 m/sec = 6 sec.

The train takes 6 seconds to cross a man standing on the platform.

6. A train 180 m long cross a tree in 10 seconds. Find the speed of the train in km/hr?

Solution:

Given that a train 180 m long cross a tree in 10 seconds.
So, from the given data, the length of the train is 180 m and time = 10 seconds.
We know that Length of the train = speed × time
Speed = Length of the train/time
Speed = 180 m/10 seconds
The speed = 18 m/sec
The speed of the train = 18 m/sec.
Now, convert m/sec into km/hr.
Multiply m/sec with 18/5 to convert it into km/hr.
m/sec × 18/5 = km/hr
18 m/sec × 18/5 = 64.8 km/hr
The speed of the train is 64.8 km/hr.

The train travels at a speed of 64.8 km/hr to cross a tree in 10 seconds.

7. A train is running at a speed of 22.5 km/hr. It crosses the pole in 20 seconds. Find the length of the train.

Solution:

Given that a train is running at a speed of 22.5 km/hr. It crosses the pole in 20 seconds.
So, from the given data, the speed = 22.5 km/hr and time = 20 seconds.
The speed of the train = 22.5 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
22.5 km/hr × 5/18 = 6.25 m/sec.
Now, find the Length of the train.
Length of the train = speed × time
Length of the train = 6.25 m/sec × 20 sec
The Length of the train = 125 m

The Length of the train is 125 m that crosses a pole in 20 seconds.

8. A train 80 m long is running at a uniform speed of 36 km/hr. How much time will it take to cross a pole?

Solution:

Given that a train 80 m long is running at a uniform speed of 36 km/hr.
So, from the given data, speed = 36 km/hr, and the Length of the train is 80 m long.
The speed of the train = 36 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
36 km/hr × 5/18 = 10 m/sec.
Now, find the time taken by the train to cross a pole.
Time taken by the train to cross a pole = length of train/speed of the train.
Time taken by the train to cross a pole = 80 m/10 m/sec = 8 sec.

The train takes 8 seconds to cross the pole.

9. A train is running at a speed of 120 km/hr. It crosses the tower in 18 seconds; find the length of the train?

Solution:

Given that a train is running at a speed of 120 km/hr. It crosses the tower in 18 seconds.
So, from the given data, speed = 120 km/hr, and the time taken by a train is 18 seconds.
The speed of the train = 120 km/hr.
Now, convert km/hr into m/sec.
Multiply km/hr with 5/18 to convert it into m/sec.
km/hr × 5/18 = m/sec
120 km/hr × 5/18 = 33.33 m/sec (approximately).
Now, find the Length of the train.
Length of the train = speed × time
Length of the train = 33.33 m/sec × 18 sec
The Length of the train = 600 m

The Length of the train is 600 m that crosses a tower in 18 seconds.
