Length of train , L = 480 m .

The train crosses a platform in 140 seconds .

To Find :

The speed of the train .

Solution :

We know , speed is given by the ratio of distance covered and time taken .

So , $v=\dfrac{L}{t}$

Putting all value in above equation .

We get :

$v=\dfrac{480}{140}\ m/s\\\\v=3.43 \ m/s$

Hence , this is the required solution .
