Problema Solution
A plan flying the 3458 mile trip from New York City to London has a 50mph tailwind. The flight's point of no return is the point at which the flight time required to return to New York City is the same as the time required to reach London. If the speed of the plane in still air is 360mph, how far is New York City from the point of no return? (Round to nearest hundredth)
Answer provided by our tutors
The speed tailwind = 50+360 = 410 mph
The speed upwind = 360-50 = 310 mph
We assume the distance of New York City from the point of no return is x km.
So the equation is
x/310 = (3458-x)/410
So
x = 1488.9
So the distance of New York City from the point of no return is 1488.9 km
