Question 1026096

two cars are traveling and leave in opposite directions at the same time. One car is traveling 20 mph faster than the other car. After 6 hours they are 780 miles apart. what is the speed of the two cars?

I have tried to divide 780 by 6 then subtract 20 to find the speed, but im not sure that's how you are supposed to solve this question.
<pre>Partially right!! I'm assuming they started from the same point, as opposed to a certain distance apart
When you divided 780 by 6, you got the combined speeds of the 2 cars
Let the slower car's speed be S
Then faster car's speed = S + 20
We then get: S + S + 20 = 130
2S = 110
S, or speed of slower car = {{{110/2}}}, or {{{highlight_green(matrix(1,2, 55, mph))}}}
Speed of faster car = 55 + 20, or {{{highlight_green(matrix(1,2, 75, mph))}}}
