How many hours will it take to complete a 90-km bike ride if you go 20 km per hour the whole time?
Answer provided by our tutors
let
d = 90 km the distance traveled
v = 20 km/hr the speed
t = the time of the travel
the speed = distance/time that is
v = d/t multiply both sides by t/v
t = d/v
t = 90/20
t = 4.5 hr
it will take 4.5 hours to complete the 90 km bike ride.
