Question 41086: two cars leave the same point traveling in opposite direction. the second car travels 10 mph fasterthan the first and after 3 hours they are 330 miles apart. how fast is each car traveling?thanks very much Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Let the slower car travel at a rate of r. The faster travels at a rate of r+10.
We always use rate*time = distance in these travel problems.
Here their combined distance after 3 hours is 330 miles...so
3r + 3(r+10) = 330
3r + 3r + 30 = 330
6r + 30 = 330
6r = 300
r = 50
r+10 = 60
