Two planes have a cruising speed of 750 km/h without wind. The first plane flies for 13 hours against a constant headwind. The second plane flies for 11 hours in the opposite direction with the same wind (a tailwind). The second plane flies for 250 km less than the first plane. Determine two equations that could be used to solve for the wind speed, w, and the distance traveled by the first plane, d. 1. (750+w)(13)=d (750+w)(11)=d+250 2. (750āw)(13)=d (750+w)(11)=dā250 3. (750+w)(13)=d (750āw)(11)=dā250 4. (750āw)(13)=d (750āw)(11)=d+250
