Question 1024556: Two cars leave Atlanta at the same time. One is traveling north and another is traveling south at a rate 5mph faster than the north-bound car. After 3 hours they are 495 miles apart. How fast is each traveling?
Answer by fractalier(6550) (Show Source): You can put this solution on YOUR website!
Call the slower car's rate, r. The faster is moving at r+5.
Now rate times time equals distance, or rt=d.
The time is 3 hours for each car.
Thus we can write
3r + 3(r+5) = 495
3r + 3r + 15 = 495
6r + 15 = 495
6r = 480
r = 60 miles per hour
r+5 = 65 miles per hour
