Let the number of hours flying downwind==H

18H ==Distance travelled downwind.

[18H - 5] / 15 ==18H/18

**H == 5/3 - hours spent flying downwind**

**[18*5/3 - 5] / 15 + 5/15==2 - hours spent flying back to its nest.**

**Total distance==[5/3 * 18] * 2 ==60 miles.**

**5/3 + 2 == 11 / 3 ==3 hours + 40 minutes - total time spent flying back and forth.**
