One of them can go twice as fast as the other. If they met two hours after starting, then when is the average speed of each cyclist. Show your work.

Combined speed of both cyclists = x + 2x Speed = Distance/Time x + 2x = 90/2 Eliminate the fraction by multiplying by 2 2x + 4x = 90 6x = 90 x = 15 Therefore 2x = 30 ANS 15 and 30

15 mph and 30 mph No work to show - did it in my head.

Let one speed be x and the other 2x 90/2 = 3x x = 15 2x = 30
