A bus traveled from the airport to the train station at a speed of 35 mph and returned at a speed of 40 mph. If the entire trip took 15 hours, find the distance from the airport to the train station?
---------
Avg speed for the round trip is
2*35*40/(35+40) = 2800/75 mi/hr = 112/3 mi/hr
---------
d = r*t = (112/3)*15 = 560 miles
One way = 280 miles
