Question

a maximum speed of train is 90km/h.it takes 10 hour to cover a distance of 500 km. find the ratio of its average speed to maximum speed

Answer 1

Average speed = 500/10 = 50km/hr
max speed = 90km/hr

ratio= avg/ max = 50/90 = 5/9

Answer 2

Maximum speed = 90km/h
Time = 10h
Average speed = Average distance /time
=500/10
=50km/h
Here the ratio of Maximum speed =90/50
=9/5 means
= 9:5
