Two cyclists leave a city at the same time, one going east and the other going west.
The west bound cyclist bikes at 12 mph faster than the east bound cyclist. After 2 hours they are 60 miles apart.
How fast is each cyclist riding?
~~~~~~~~~~~~~~~~~~~~~~
One cyclist has the speed x, the other has the speed x+12.
The distance equation is
2x + 2(x+12) = 60.
Solve for x.
