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!

**bobpursley**, Sunday, February 1, 2009 at 12:39pmJ=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.
