Question

(solve this question please)

A train is 100 meter long and is running at the speed of 30 km per hour. Find the time it will take to pass a man standing at a crossing

Answer 1

To calculate time, u need distance and speed.
Here distance will be the length of the train
=100m
Speed=30kmph
          =30*5/18
          =33.33mps
Time=Distance/Speed
        =100/(100/3)
        =3s

Answer 2

speed =distance / time
time ×speed =distance
time =distance /speed
=100/30000
=1/300
=0.00333
