Question

A bike covers a certain distance at the speed of 64 km/h in 8 hours. If the bike was to cover the same distance in approximately 6 hours, at what approximate speed should the bike travel?

Answer 1

total distace=speed×time
distance=64×8
distance =512km
if he want to cover in 6hrs so time =6hrs
then speed=distance /time
speed=512/6
speed=85.33km.
so he has to travel with 85.33 km/hr

Answer 2

Initial speed covered by the bike =>64km/h
Time taken = 8hr
Distance1 = speed × time = 64×8= 512km
According to the question
Distance 1 = distance 2
Distance 2 covered in 6 hrs =>512km
Speed = distance/time = 512/6=>85.33km/hr

Hope it will help you
