Two cars leave Denver at the same time and travel in opposite directions. One car travels 10mi/h faster than the other car. The cars are 50mi apart in 5h. How fast is each car traveling?
------
Let the speed of the slower car be x mph.
Then the speed of the faster car is x+10 mph.
----
The cars are separating at a combined speed of 2x+10 mph.
-----
Equation:
speed = distance / time
speed = 50 mi/5 hr
speed = 10 mph
---
2x+10 = 10
2x = 0
x = 0
x+10 = 10
---
One of the cars is not moving.
The other's speed is 10 mph.
