A plane flying the 3020-mile trip from City A to City B has a 60-mph tailwind.
The flight's point of no return is the point at which the flight time required to return to City A is the same as the time required to continue to City B.
If the speed of the plane in still air is 430 mph, how far from City A is the point of no return? Round your answer to the nearest mile.
Let x = distance from city A
(3020-x) = distance from city B
Write a time equation: time = dist/speed
Continue time = return time
490x = 370(3020-x)
490x = 1117400 - 370x
490x + 370x = 1117400
860x = 1117400
x = 1299 mi from A is the point of no return
Check solution by finding the times
1299/370 = 3.5 hrs to return to A
(3020-1299)/490 = 3.5 hrs to continue to B
