A woman can bicycle 66 miles in the same time as it takes her to walk 24 miles. She can ride 7 mph faster than she can walk. How fast can she walk?
Using r as your variable to represent the rate at which she walks, write an equation using the information as it is given above that can be used to solve this problem.

Since time = distance/speed,
66/(r+7) = 24/r
