Question 568661: Two cars leave the same place at the sametime. the car traveling west is going 9mph faster than the car going east. at the end of 8 hours, the cars are 1032 miles apart. How fast are the cars going? Answer by solver91311(24713) (Show Source):
Distance equals Rate times Time, therefore Rate must equal Distance divided by Time.
The combined rate must then be 1032 divided by 8. If one of the cars is going miles per hour, then the other car must be going miles per hour. They are going in opposite directions, so the rate at which they are moving apart is the sum of their speeds. Set equal to the result of the combined speed calculation above. Solve for and then calculate .
