Question

Anuj takes 15 minutes to go to the school and 20 minutes to come back from the school by bicycle if school is 4.5 km away from home find his average speed​

Answer 1

Answer:

15.75km/h

Step-by-step explanation:

distance = 4.5km

speed for going = (4.5*60)/15

                         = 18 km/h

speed for coming = (4.5*60)/20

                              = 13.5km/h

average speed = (18+13.5)/2

                            = 15.75 km/h
