**PsyDAG**, Friday, October 5, 2007 at 11:36amLet Doreen's speed = x and Sue's = x + 19.

Let y - 4 = Doreen's time and y = Sue's time

Speed = distance/time

x = 175/(y-4) (Doreen)

x + 19 = 66/y (Sue)

Substitute the value of x from the first equation into the second and solve.

I hope this helps. Thanks for asking.
