Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hr. One car travels 4 mph faster than the other. what is the average speed of each car?
.
Let x = speed (mph) of slower car
then
x+4 = speed of faster car
.
2(x + x+4) = 190
(x + x+4) = 95
2x+4 = 95
2x = 91
x = 45.5 mph (speed of slower car)
.
speed of faster car:
x+4 = 45.5+4 = 49.5 mph
