Question

A boy cycled at an average speed of 21 km/h for 40 minutes. What distance did he cover? please may i have the answer

Answer 1

Step-by-step explanation:

speed = 21 km/h

time     = 40 min

            =  40/60 = 2/3 hr

distance = speed * time

               = 21 * 2/3

               =  7*2

              =  14

hence the distance covered by the boy is 14 km or 14*1000 = 14000 m    

           

             

Answer 2

14 km

Step-by-step explanation:
