Homework Help: Algebra

Jodie bicycles 5 km/h faster than Robert. In the same time it takes Robert to bicycle 39 km, Jodie can bicycle 54 km. How fast does each bicyclist travel?

I was out of school last week with the flu, and I am trying to do this makeup work but I have no idea how to solve this. I dont need an answer, but if any one can tell me how to solve it I would appreciate it.

Thanks!

J=R-5 where J,R are in km/hr

Time=distance/velocity

distanceJodie/J=distanceR/R
54/J=39/R

54R=39J
then put in for J, (R-5) and you can solve it.
