Question 478377: Ben and David both cycled a distance of 24km. They started at the same time. David completed it earlier than Ben 20 minutes. If davids average speed was 9km/h find bens average speed. Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! David's average speed was 9 kph:
9 kph x 1/3 hour =3 kilos
David's time: 24/9=2.66 hours
Ben's time: 2.66+.33 hours =3 hours
24/3=8 kph
Ben traveled at 8 kilometres/hour..
