Question

A train is 180 m long If it runs at a speed of 90 km/hr how long will it take to pass an electric pole​

Answer 1

Answer:

t = 2 seconds

Explanation:

Given that,

The length of a train, d = 180 m

The speed of the train, v = 90 km/hr = 25 m/s

we need to find the time will take to pass an electric pole. Let the time is t. So, it can be calculated as follows :

$t=\dfrac{d}{v}\\\\t=\dfrac{180\ m}{90\ m/s}\\\\t=2\ s$

So, the required time is 2 seconds.
