Pythagoras Theorem

A train 140...

Question

A train $140$ m long travelling at a uniform speed passes a stationary man in $4$ seconds. Find the speed of the train in km/hr.

Open in App

Solution

140 m is traveled in 4 seconds according to the stationary man
$v = \frac{D i s t a n c e}{T I m e} = \frac{140}{4} m / s = 35 m / s$

Now, $35 m / s = 35 * \frac{1000}{3600} = 9.72 k m / h r$
