#### Question

A car travels a distance of 15 km in 20 minute. Find the speed of the car in  km h-1.

#### Solution

istance travelled by car =15 km
Time taken = 20 minutes
(i) Speed of car in km h-1
Convert 20 minutes to hour

1 minute = 1/60 hour

∴ 20 minutes = (1 × 20)/ 60 = 1/3 hour

Speed of car   =  (Distance)/(Time   taken )

= (15  km  )/( 1/3  h)

= 15 km × 3h^-1 = 45 km h^-1 = 45 km h^-1

Is there an error in this question or solution?
