An eagle can fly 20 mph in still air. Flying with the wind, the eagle can fly 8 miles in the same time that is required to fly 6 miles going against the wind. Find the rate of the wind.



Answer :

Answer:

Step-by-step explanation:

distance divided by rate = time

given:

 8 / ( 20 + w) = 6 / (20-w)           where w is wind speed

Cross multiply

160 - 8w = 120 + 6w

40 = 14 w

w = 40 / 14  m/hr = 2.857 mph
