Problema Solution
oceanic flight 815 can fly 624 miles with the wind in 3 hours, while it takes the same plane 4 hours to fly the same distance against the wind. Find the speed of the plane in still air, and the speed of the wind.
Answer provided by our tutors
let speed of plane = x and speed of wind =y
we get two equations
3x + 3y = 624
and 4x - 4y = 624
solving
we get
speed of plane = 182
and speed of wind = 26
