Question

with a speed of 60 km hr a train crosses a pole in 24 sec find the length of the train ​

Answer 1

The length of the train is 400 m.

Given data:

The speed of the train is 60 km per hour. It crosses a pole in 24 seconds.

To find:

The length of the train

Tips for solution:

Since the pole has smaller diameter or width compared to the train, that length can be ignored.

Step-by-step explanation:

• 60 km = 60 × 1000 m = 60000 m
• 1 hour = 60 minutes = 60 × 60 seconds = 3600 seconds

In 3600 seconds, the train goes 60000 m

In 1 second, the train will go $\dfrac{60000}{3600}$ m

In 24 seconds, the train will go

$\dfrac{60000}{3600}$ × 24 m

= 400 m

So the train is 400 m long.
