Download question setAnswersAverage Speed = 100 km/hr.

With this speed, train can cover 600 km in 6 hours but train used to stop for 3 minutes after every 75 km.

So, Train will stop = 600/75 = 8 times in the whole journey.

But, you need to understand that after 7th stopping train will be at the destiny in next stop. Therefore, train will stop 7 times in journey.

So, extra time = 7 *3 = 21 minutes.

Total time taken in the journey = 6 hour 21 minutes.
