Two planes leave New Orleans at the same time. Plane A heads north and Plane B heads south. After 4 hours and 15 minutes, the two planes are 4568.75 miles apart. Also, Plane A is traveling 53 mph faster than Plane B.

Question

At what speeds are the two planes traveling at?

How far did each plane travel?

Answer 1

If B's speed is x, the A's speed is x+53
Since distance = speed*time, we have

4.25(x + x+53) = 4568.75
