You can put this solution on YOUR website! 2 cars start from towns 480 mi apart and travel toward each other. they meet after 4hr. find the speed of each car if one travels 10 mph faster than the other.
***
let x=speed of slower car
x+10=speed of faster car
x+x+10=2x+10=speed at which 2 cars are approaching each other
distance /speed=travel time
480/(2x+10)=4
8x+40=480
8x=440
x=55
x+10=65
speed of slower car=55 mph
speed of faster car=65 mph
