Question

PLEASE HELP ME!

The airspeed of a plane is its speed through the air. The groundspeed of a plane is its speed relative to the ground. The groundspeed of an airplane is affected by the speed of the wind. Suppose that a plane flying 2000 miles west requires 10 hours and flying 2000 miles east requires 8 hours. Find the airspeed of the plane and the effect wind resistance has on the plane.

Answer 1

going west average speed is
2000/10 = 200 mph

going east is
2000/8 = 250 mph

the plane is the average of the extremes or 225 mph

the effect of the wond is 250-225= 25 mph
