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

t = 2 seconds

Step-by-step 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=(d)/(v)\\\\t=(180\ m)/(90\ m/s)\\\\t=2\ s`

So, the required time is 2 seconds.
