a passenger plane left Tokyo and flew south. 2 hours later a jet left flying at 275 mph in an effort to catch up to the passenger plane. After flying for 9 hours the jet finally caught up. Find the passenger plane's average speed.
***
let x=passenger plane's average speed.
travel time of passenger plane=2+9=11 hrs
distance=travel time*speed (equal for both planes)
..
11x=9*275
x=225
passenger plane's average speed=225 mph
