Question

The average speed of a train is 4 1/3 times the average speed of a tractor. The tractor covers 270 km in 15 hours. How much distance will the train cover in 12 hours?

Answer 1

speed of tracter=270/15=18km/h
average speed of train =4 1/3 of that of tracter
=13/3 ×18
=13×6=78km/h
so distance covered by it in 12 hours=78×12=936km
