Question

Aimee is flying a plane for the first time! The air traffic controller tells her to fly at 500 m above the ground or higher. Write an inequality that is true only for elevations (h) at which Aimee should fly.

Answer 1

We are given in this item that the elevation required for flying a plane is 500 m or higher. This concept can also be expressed as, ''elevation must be at least 500m''. Further, this can be expressed as,
                     ''elevation should be greater than or equal to 500m''

If this is to be translated to the mathematical inequality, the answer would be,
                               h ≥ 500 m
