Question 117

A train crosses a platform in 30 seconds travelling with a speed of 60 km/h. If the length of the train be 200 metres, then the length (in metres) of the platform is

Solution

Let the length of train and speed of train be L meter and S m/sec . let the length of platform be P meter

It is given that L = 200 m

Time (T) = 30sec

S = 60 x $$\frac{5}{18}$$ = $$\frac{50}{3}$$ m /sec

using ,

(L+P) = S x T

(200 + P) = $$\frac{50}{3}$$ x 30

P = 300 m
