 Algebra problems concerning airplane velocity and headwind can take many forms. Here are 6 types of such problems. A) Solving for Airplane and Wind Velocity given Distance and Time Example: Travelling against the wind, an airplane takes 3 hours to travel 1,650 miles. On the return trip, the airplane travels with the wind, and takes 2 hours 45 minutes (or 2.75 hours) to travel 1,650 miles. What is the speed of the airplane in still air and the speed of the wind? Using the calculator, we click "A" then enter Distance   1650 Time 1   3 Time 2   2.75 (entering Time 1 = 2.75   Time 2 = 3 will also work) Clicking "Calculate" we see the answers are: Airplane Velocity   575 Wind Velocity     25
