A plane flying the 3458-mi from New York City to London has a 40-mph tailwind. The flight's point of no return is the point at which the flight time required to return to New York is the same as the timerequired to continue to London. If the plane's speed in still air is 840 mph, how far is New York from the point of no return?

The distance from New York to the point of no return is \( \square \) mi. (Round to the nearest integer.) 

Answer

Suppose the time from the point no return to London is x hours

(840-40)x+(840+40)x=3458

x\(\approx 2.083\)

The distance:1666mi
