Two cars start from towns 570 mi apart and travel toward each other. They meet after 6 hr. Find the speed of each car if one travels 15 mph faster than the other.
-----
slower car rate:: x mph
faster car rate:: x+15 mph
combined speed:: 2x+15 mph
------
Equation:
rate = distance/time
----
2x+15 = 570/6
----
2x + 15 = 95
2x = 80
x = 40 mph
x+15 = 55 mph
