Question

A train crosses a pole in 6.4 seconds and a 220 metres long platform in 15.2 seconds.What is speed of train

Answer 1

Explanation:

let the distance x m

Condition 1

t = 6.4

d= x

than speed = x/6.4

condition 2

t= 15.2 d = x +220

s = x +220/15.2

than both are equal

x/6.4 =x +220/15.2

solve it you get speed

and is 160m per sec
