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

Hi There!
Solve the Inequality:
2x-1≤x+5
Move all the variables (in this case, x's) to the left, using the opposite operation:
2x-x-1≤5
Move -1 to the left:
2x-x≤5+1
Combine like terms:
