Question 155080: Two cars are traveling toward each other and are 455 miles apart. One car is going 10mph faster than the other. They meet after 3.5 hours. How fast is each car going? Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! 3.5(x+x+10)=455
3.5(2x+10)=455
7x+35=455
7x=455-35
7x=420
x=420/7
x=60 mph for the slower car.
60+10=70 mph for the faster car.
Proof:
3.5(60+70)=455
3.5*130=455
455=455
