Question 8

A goods train runs at a speed of 72 km/hr and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

Solution

Trains speed =$$72\ \frac{km}{h}=\frac{72000}{3600}=20\ \frac{m}{s}.$$

So, in 26 sec , it will cover =$$26\times\ 20\ m=520\ m.$$

It covers platform's length and train's length in 26 secs.

So, Trains length= $$\left(520-250\right)=270\ m.$$

D is correct choice.
