Question

A 320 m long train is running at 72 km/h. How much time will it take to cross a tree?

Answer 1

Time = distance/speed
=320/72
= 4.4

Answer 2

Solution:

It is given that a train 320 m long train is running at 72 km/h.

• Length of train = 320 m
• Speed of Train = 72 km/hr or 20 m/s

So, we have to find the much time will it take to cross a tree.

We know, Distance = Speed × Time

Time = distance/Speed

Time = 320 / 20

Time = 16 seconds

Therefore, 16 Seconds time will it take to cross a tree.
