You can put this solution on YOUR website! Two cars, which are 636 miles apart and whose speeds differ by 2 miles per hour, are moving toward each other.
If they meet in 6 hours, find the speed of each car.
:
Let s = speed of the slower car
then
(s+2) = speed of the faster car
:
Write a distance equation; dist = time * speed
6s + 6(s+2) = 636
6s + 6s + 12 = 636
12s = 636 - 12
12s = 624
s = 624/12
s = 52 mph is the slower car
then, obviously
54 mph is the faster
:
:
Check this find the distance each traveled
6 * 52 = 312 mi
6 * 54 = 324 mi
---------------------
total dist 636
