Question

An airplane descends 1.8 miles to an elevation of 6.75 miles. Find the elevation of the plane before its descent.

Answer 1

Answer: 8.55 miles

Step-by-step explanation:

Adding the totals given in the problem together:

1.8 miles + 6.75 miles = 8.55 miles.

Therefore, because we descended the plane and are looking for the previous height, we just add the descent to the elevation AFTER descent.
