Homework Help: Word problem d=rt, find average speed

  1. Apr 11, 2010 #1
    1. The problem statement, all variables and given/known data

    Jake is 1 mile per hour faster on his skateboard than Tom. Both skate 24 miles one day from the park to the mall. Tom took 2 hours longer than Jake. What was Tom's average speed?

    2. Relevant equations

    3. The attempt at a solution
    So I set up a table w/ d=24, rate for Jake x+1 and rate for Tom equal to x. and then for time I know Tom took 2 hours...but I cant seem to piece all this information into an equation that works! Any help would be great.

    What expression represents Jake's time? Tom's time? What can you do to make an equation, given that Tom's time was 2 hours longer than Jake's time.

    BTW, that's a long way to go on a skateboard...
