Putting extra spacing in your question to make it look larger and double posting are both strategies that will get you ignored. Instead, put your effort into following the rules for posting:

Rules for posting:
1. If you post a problem for which you want a solution, make sure you make it clear what it is about the problem that is giving you difficulty.

2. Show all of the work, successful or not, that you have done or attempted in the solution of the problem.

            SPEED          TIME           DISTANCES

DOUG           r             3

ASHLEY         r           2%261%2F2

TOTAL                                       341

Use RT=D to fill in the missing cells for the distances. Form the sum equation for the total distance. Solve for r.


That means,
            SPEED          TIME           DISTANCES

DOUG           r             3             3r

ASHLEY         r           2%261%2F2     %285%2F2%29r

TOTAL                                       341
