Question

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?

Answer 1

Try a three system equation in which the first is Suzuki's bike time, 9x = z, x being the factor you'd multiply his average speed by to get his distance (his time on the bike); 36y = z; and 9x=3(36)x. Or something similar.

Answer 2

*9x=3(36)y

Answer 3

can you reword that?
