Question

a train 28 M long is running at the speed of 42 kilometre per hour how much time will take to pass a man standing on a platform​

Answer 1

Answer:

Distance = Speed × Time

here, D= 28m

S=42km/h =42 × 5/18 =35/3 m/s.

T= D/S

= 28/35/3

= 28×3/35

= 12/5

= 2.4 sec

So, the train will take 2.4 sec to pass the man.
