You can put this solution on YOUR website! At 10:00 am, a car leaves a home at a rate of 60 mi/h. At the same time, another care leaves the same home at a rate of 50 mi/h in the opposite direction.
At what time will the cars be 330 miles apart?
:
You can do this in your head, the relative speed of the two cars is the sum which is 110 mph, divide that into 330 and get 3 hrs, 1 PM is answer
:
However, they may want you to show some equations here
:
Let t = time for this to be true;
write a distance equation, dist = speed * time
60t + 50t = 330
solve for t
