meets a train that travels in the same direction at the crossing. One
day he was late by 20 minutes and met the train 7 miles ahead of the level crossing. Can you figure out the speed of the train?

- 63,375 mph
Man meets train 7 miles ahead from normal meeting point where he reaches 160/13 minutes before normal meeting time.
So train will cover 13 miles in 160/13 minutes.
so speed of train = 13*13*60/160 mph = 63.375 mph - 12 years agoHelpfull: Yes(1) No(2)
