You can put this solution on YOUR website!
Let r = speed of slower car.
Know that the faster car goes at speed, r+5.

CAR__________speed___________time___________distance
SLOW__________r______________2______________r*2
FAST__________r+5____________2______________(r+5)*2
Total_______________________________________170

Helpful Comments:
Total does not apply to speed.
Total does NOT apply to time.
Total works for the sum of the distances each car traveled during the two hour period.
The asterisk, *, is used for indicating multiplication.

EQUATION FOR SITUATION:
highlight%28r%2A2%2B%28r%2B5%29%2A2=170%29
Solve the equation for r.
