Time, Rate, Distance Question?
You drive 90 miles along the Pacific Coast Highway and then take a 5-mile run along a hiking trail in Point Reyes National Seashore. Your driving rate is nine times that of your running rate. If the total time for driving and running is 3 hours, find the average rate for driving and the average rate for running.

Time for driving = 90 mi/9r
Time for running = 5/r
Total time = 3 h
3 = 90/9r + 5/r
3 = 10/r + 5/r
3 = 15/r
r = 5 mph = running rate
9r = 45 mph = driving rate
