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 don't 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.
