A plane flies around a square of side 10 km with wind of 30 km/h; the plane's speed in still air is 50 km/h. Its total time when the wind blows along one side of the square is:

Answer:

67.50

Solution:

$T = \frac{2 \times 10 \times ( 50 + 2500 - 900 )}{2500 - 900} = \frac{20 \times 90}{1600} = 1.125 h = 67.5 min$ .
