1. The problem statement, all variables and given/known data A plane flies flies into a 65 mi/h headwind. On the return trip from B to A, the wind velocity is unchanged. The trip from B to A takes 65 min less than the trip from A to B. What is the airspeed (assumed constant) of the plane? a. 480 mi/h c. 530 mi/h b. 610 mi/h d. 400 mi/h 2. Relevant equations ? 3. The attempt at a solution 65 min = 1.08 hrs time from A to B = 2300 mi / 65 mi/hr = 35.4 hrs time from B to A = 35.4 hrs - 1.08 hrs = 34.4 hrs Not sure if I am doing it correctly and not sure where to go from here.
