Question

An express train travelled at an average speed of 100 km/hr, stopping for 3 minutes after every 75 km. How much time does the train take to travel between two places which are 600 km apart ?

Answer 1

Answer:

6 hours 24 minutes.

Explanation:

Average speed of 100kmph, distance of 600km:

Time = 6 hrs (600/100).

But, for every 75km, 3 extra minutes are taken:

So: Total time = Time + Extra time

Extra time = 3 minutes * Total distance/75km = 3 minutes * (600/75) = 3 minutes * 8 = 24 minutes.

Total time = 6 hours 24 minutes.
