Jim can run 4 miles in 1.5 hours. How many miles can he run in 4 hours

If jim can run a distance of 4 miles in 1.5 hours where distance=rate x time, we must first find his rate. 4=r (1.5) > 4/1.5=2.66 miles/hour. then we take his rate 2.66 and multiply it by the time of 4 hours to find his total distance. d=2.66 (4), where his distance is 10.66 miles or 10.7 miles
