Flight Problem

1) A plane is flying 2400 miles from San Francisco to Hawaii. It is flying at a speed of 600 mph, and there is a tailwind blowing at 40 mph.

2) How many hours after takeoff would it be faster to keep on flying to Hawaii than to turn around and fly back to San Francisco if an emergency occurred on board?

The general formula for this type of problem is:

To solve the problem, we know the speed at which the plane is flying in each direction: for San Francisco to Hawaii this is 600 mph + a tailwind speed of 40 mph giving a total speed of 640 mph; flying from Hawaii bac
