Question 1051818: 2 cars leave a city. One is traveling east at 66 mph and the car going west is traveling at 62 mph. How long will it take for them to be 704 miles apart?
I went ahead and figured out how many miles each car has to drive before they will be 704 miles apart by dividing 704 by 2 to get 351 miles. I'm just having trouble figuring out how to break down this problem to solve it after that. I'm not even sure if dividing 704 by 2 was the right first step. I am just mostly unsure of how to break down this problem to figure it out.
