Problema Solution
A small plane can fly at 110 mph in calm air. Flying with the wind, the plane can fly 260 mi in the same amount of time as it takes to fly 180 mi against the wind. Find the rate of the wind.
Answer provided by our tutors
The rate of wind is x mph
The equation is
260/180 = (110+x)/(110-x)
So
x = 20
So rate of wind is 20 mph
