You can put this solution on YOUR website! two cars start from towns 360 mi apart and travel towards each other. they meet after 4 hr. find the speed of each car if one travels 10 mph faster than the other.
-------
slower car DATA:
time = 4 hr ; rate = x mph ; distance = 4x miles
-----
faster car DATA:
time = 4 hrs ; rate = x+10 mph ; distance = 4x+40 miles
=========
Equation:
distance + distance = 360 miles
4x + 4x+40 = 360
8x = 320
x = 40 mph (speed of the slower car(
x+10 = 50 mph (speed of the faster car)
-----------
