2x - 20 = 32
2x - 20 + 20 = 32 + 20
2x = 52
/2 = /2
x = 26
0,3 3,3 2,3 and 1,2 (from A to D)
Answer:
Velocity (against wind) = 1,890 / 3 = 630 mph
Velocity (with the wind) = 1,890 / 2.5 = 756 mph
Plane speed (still air) = 630 + wind speed
Plane speed (still air) = 756 - wind speed
Adding both equations equals
2 * Plane speed (still air) = 1,386
Plane Speed = 693 mph
