You can put this solution on YOUR website! A round trip helicopter ride lasted 4 hours and 30 minutes. If the helicopter flew away from the airport at 100 mph and returned at the rate of 50mph, what was its greatest distance from the airport?
------------
Avg speed of a round trip = 2*r1*r2/(r1 + r2)
= 2*100*50/150 = 200/3 mi/hr
--------
d = r*t = (200/3)*4.5 = 300 mile RT
--> 150 miles each way
