Question

a train 150 m long is running at a speed of 90 kilometre per hour find the time taken by the train to cross a tree

Answer 1

Solution:-
Length of train =150m
Means, distance=150m
Speed=90km/h
To convert it in m/s ,we will multiple it by5/18
$= > 90 \times \frac{5}{18} \\ = > 25$
Speed=25m/s

Now,
$time = \frac{distance}{speed}$
So,
$time = \frac{150}{25} \\ = > 6$
Hence,
Time taken to cross a tree is 6 second.

Answer 2

Answer:

time taken to cross the tree is 6 second
