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

  Is there an error in this question or solution?
