Question

A train leaves delhi at 9:00 am and reaches Jaipur which is at a distance of 260km at 12:45pm the train reaches alwar [at a distance of 150km from delhi] at 11:30 am and stop there for 15 minutes what is the average speed of the train between Alwar an Jaipur.

Answer 1

the speed comes out to be 30.55m/s because the train reaches alwar which is 150 km from delhi hence it has to cover 110 km more to reach jaipur hence the total distance is 110 km or 110000 mtr and the time will be 60 min. because train starts from alwar at 11:45 because it stops for 15 min at alwar hence total time is 3600 seconds hence the average speed is 110000/3600 which is 30.5m/s
