Question

If Joe drives 50 mph for 0.5 hours and then 60 mph for 1.5 hours, then how far did he drive?

Answer 1

115 mi

Explanation:

speed = distance/time

distance = speed * time

0.5 hours at 50 mph

distance = 50 mph * 0.5 h = 25 mi

1.5 hours at 60 mph

distance = 60 mph * 1.5 h = 90 mi

total distance = 25 mi + 90 mi = 115 mi
