Question

Karl rides his bicycle 120 feet in 10 seconds. How many feet does he ride in 1 minute?

Answer 1

120/10=x/60
120*60=10*x
720/10=x
72=x
Karl can 72ft in 1min

Answer 2

Since he rides 120 in 10 seconds you need to multiply that by 6. 10 is only 1/6 of a minute. He will go 720 feet in one minute.
