Answer:

  2.5 hours

Step-by-step explanation:

The product of speed and time is distance. If the distance is the same, then time is inversely proportional to speed. At 60/50 = 6/5 times the speed, the return trip will take 5/6 times the time:

  (5/6)(3 hours) = 2.5 hours . . . time for return trip
