Question

Two trucks leave a warehouse at the same time. one travels due west at an average speed of 49 miles per hour, and the other travels due east at an average speed of 65 miles per hour. after how many hours will the two trucks be 513 miles apart?

Answer 1

Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.

So we can just keep adding the distance as we know they are in different directions. 49 + 65 = 114. So 114 * 4.5 = 513 miles. SO after around 4.5 hours they will be 513 miles apart.
