A plane flies at 190 mph for the first and last half hour of a flight. It flies at a higher constant speed for the rest of the flight. The route is 2090 miles. The plane is 990 miles from the destination 2 hours before the end of the flight.

An airplane, flying with a tailwind, travels 1060 miles in 2 hours. The return trip, against the wind, takes 2 and 1/2 hours. Find the cruising speed of the plane and the speed of the wind (assume that both rates are constant). Cruising speed of the plane = _____ mi/hr Speed of the wind = ______ mi/hr
