Question

A train traveling at 60 kmph takes 27 seconds in passing a certain point. find the length of the train

Answer 1

D= s× t= 60× 5/18×27 = 450meter will be the answer

Answer 2

60kmph

⇒ 1 hour = 60 km

Find the distance in metre:

1 hour = 60 km

1 hour = 60,000 m

Find the distance traveled in 1 min:

60 min = 60,000 m

1 min = 1,000 m

Find the distance traveled in 1 second:

60 sec = 1000m

1 sec = 1000/6 = 50/3 m

Find the distance traveled in 27 seconds:

1 sec = 50/3 m

27 sec = 50/3 x 27 = 450 m

Answer: The length of the train is 450 m
