Question 456259: 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 45 miles per hour, how long will it take to drive the same distance at 30 miles per hour?

D = (2 h)(45 mph) = (30 mph)t
This is an inversely proportional rate since the distance (rt) is constant.
Solving for t, we get t = 3 hours.
