**PsyDAG**, Wednesday, March 24, 2010 at 11:29amC = 2J (rates)

Distance = rate/time

Therefore, time = rate/distance

J/24 - C/24 = 3

Use substitution to solve first for cyclist and then for jogger.

**PsyDAG**, Friday, March 26, 2010 at 7:52pmSorry, I goofed!

Distance =**rate * time**

Therefore, Time = Distance/rate

24/J - 24/C = 3

Substitute 2j for C.

24/j - 24/2J = 3

Multiply both sides by J.

24 - 12 = 3J

12 = 3j

4 = J

C = 2J = 2 * 4 = 8

Sorry for the goof! This should help.
