Question

A train passes a station in 36 s and a man standing on the platform in 20 s. If the speed of the train is 15 meters/sec the length of the platform is ———-.

Answer 1

Hey

First of change the speed into m/s that is 15 m/s
length of train 15×20= 300

using

(x+300)/36= 15

x= 240 m

Answer 2

Answer:240m

Step-by-step explanation:

Just by using S=D/T.

Find length of train = 15×20=300.

Let the length of platform be X.

So total distance is (300+X)m

By using S=D/T

36=(300+X)/15.

540-300=X

= 240m
