Question 1122891
Two cars start at the same time from two towns.
 792 kilometers apart and meet in 9 hours.
 One car can travel 8 km faster than the other car.
 How far did each car travel before they meet?
:
Find the speed of the cars
let s = speed of one car
and
let (s+8) = speed of the other car
:
Write a distance equation; dist = time * speed
9s + 9(s+8) = 792 
9s + 9s + 72 = 792
18s = 792 - 72
18s = 720
s = 720/18
s = 40 km/h for one car
and obviously
48 km/h for the other car
:
"How far did each car travel before they meet?"
Car one: 9 * 40 = 360 km
Car Two: 9 * 48 = 432 km
-----------------------------
check total dist: 792 km
