Let the speed in still air be S, and wind speed, W
Average speed during flight, against the wind = , or , or , or 160 mph. Therefore, S - W = 160 ----- eq (i)
Average speed during flight, with the wind = , or , or , or 200 mph. Therefore, S + W = 200 ----- eq (ii)
S - W = 160 ------ eq (i)
S + W = 200 ------ eq (ii)
- S + W = - 160 ------ Multiplying eq (i) by - 1 ----- eq (iii)
2W = 40 ------ Adding eqs (iii) & (ii)
W, or speed of wind = , or mph
