Question

If the speed of a motorcycle is 40 km per hour , how far will it travel in an hour and quarter

Answer 1

In 1 hr motor cycle travels = 40 km-----( 1) 

In 1/2 hr motor cycle travels = 40 / 2 km = 20 km

in a quarter hour  motor cycle travels = 40 /4 km= 10 km-----( 2) 

In 1 hour and a quarter hour motor cycle travels the distance

                                                  = ( 1) + (2 )

                                                  = 40km + 10km
                                               
                                                  = 50km
