Problema Solution
An airplain flies 1,120 kilometers with a tail wind and returns, flying into the same wind. The total flying time is 3 hours and 45 minutes and the airplanes airspeed is 600 kilometers per hour. What is the wind speed?
Answer provided by our tutors
The wind speed is x kph
So the equation is
1120/(600+x) + 1120/(600-x) = 3.75
So
x =40
So
The wind speed is 40 kph
