Question

if thé speed of a motorcycle is 40 km per hour how far will it travel in an hour and a quarter ?

Answer 1

S = 40 km /hr
D = S × T
= 40 x 1
= 40 km /hr

In an quarter
D= 40 × 1/4 of 60/60
=40 x 1/4
= 10 km / hr

Answer 2

Here the speed = 40km/h
And to find distance traveled

In first case the time = 1 hours
Speed = distance /time
= 40km/h = distance /1
= 40 = distance
Therefore distance = 40km

In second case,
The time = quarter = 1/4 of 1 hour
= 1/4 * 1 = 1/4 hrs

So, speed = distance /time
= 40 = distance /1/4
=40 = distance * 4
= 40/4 = distance
= 10 = distance

Therefore the distance = 10km
