The time that it takes you to drive a certain distance varies inversely as your driving rate. Averaging 40 miles per hour, it takes you 10 hours to drive the distance. How long would the trip take averaging 50 miles per hour? 1. Time, t, varies k inversely as rate, r. t = 2. It takes 10 hours at 40 miles per hour. k 10 40 k = 10(40) = 400 400 3. t= 4. How long at 50 miles per hour? Substitute 50 for r. 400 t = = 8 50 It takes 8 hours at 50 miles per hour.
