Question

without stoppage, a train travels at an average speed of 75 km/h and with stoppages it covers the same distance at an average speed of 60 km/h. how many minutes per hour does the train stop?

Answer 1

Answer:

A train stops on an average 12 min per hour.

Explanation:

Given that,

Without stoppage

Average speed = 75 km/h

With stoppages

Average speed = 60 km/h

We know that,

Time of rest per hour is defined as,

Time of rest per hour equal to the difference in average speed divided by the speed without stoppage.

$T = \dfrac{75-60}{75}\times60$

$T = \dfrac{15}{75}\times60$

$T = 12\ min$

Hence, A train stops on an average 12 min per hour.

Answer 2

Answer:

12 minutes

Explanation:

In a hour train travel 75km

Then in a min it will covered 60/75

Therefore 60/75*60=48 min train travel in a hour..

Hence it will stop for 12 minutes only(60-48).
