Question

The time t required to drive a certain distance varies inversely with the speed r. if it takes 2 hours to drive the distance at 30 miles per hour, how long will it take to drive the same distance at 50 miles per hour

Answer 1

(2hrs)(30mph) = x (50mph)

60 = 50x

60/50 = 50x/50

x = 1.2 hours

1 1/2 as a fraction
