Solve by elimination method.
A cabin cruiser travels 20 miles in the same time that a power boat travels 40 miles. The cruiser travels 5 mph slower than the power boat. Find the speed of each boat

Cruiser, r-5 speed, distance 20, time x;
Boat, speed of r, distance 40, time x;

Elimination not the best method for this example problem.
system%28%28r-5%29x=20%2Crx=40%29,...


Better set-up can be 20%2F%28r-5%29=40%2Fr.
