If Dr. Suzuki rides his bike to his office, he averages 9 miles per hour. If he drives his car, he averages 36 miles per hour. His time driving 1/3 hour less than his time bicycling. How far is his office?

Question

anonymous · Answer

Let the time for Dr Suzuki to ride his bike to his office be x
9x = 36 (x -1/3)

9x = 36x - 12

27x = 12

x = 12/27

9 * 12/27 = 4 miles

$$t \text { =} \frac{d}{r}$$Solve the following for d, the distance to the office:$$\frac{d }{9}=\frac{d}{36}+\frac{1}{3}$$d = 4 miles
