You’re piloting an airplane to prepare for landing you change the planes altitude from a meters to c meters.

which expression represents the distance between two altitudes

|a+c|
|a-c|
both

|a-c| meters

Step-by-step explanation:

If I am piloting an airplane to prepare for landing, I change the plane's altitude from a meters to c meters, then the expression that represents the distance between two altitudes is given by |a-c| meters, not by |a+c|.

For, example if the altitude of the plane changes from 1000 meters to 500 meters for preparing for landing then the distance between those two altitudes is |1000 - 500| = 500 meters. (Answer)

But using the expression |a+c|, I will get the wrong answer as |1000 + 500| = 1500 meters.

answer is x<
