A light plane flew from its home base to an airport 255 miles away. With a headwind, the trip took 1.7 hours. The return trip with a tailwind took 1.5 hours.
Find the average airspeed of the plane and the average wind speed.
Answer (3)
The speed from home base to airport was: v = 255 mi l es /1.7 h / : 1.7 v = 150 m p h The speed from airport to home base was: v = 255 mi l es /1.5 h / : 1.5 v = 170 m p h Average speed of plane was: 2 170 m p h + 150 m p h = 160 m p h Average speed of wind was: x − w in d s p ee d ( m p h ) 150 + x = 170 − x / + x 150 + 2 x = 170 / − 150 2 x = 20 / : 2 x = 10 Answer: Average speed of plane was 160mph and average speed of wind was 10mph.
I hope I helped :D
