Question

question 8 of 8
what is the possible altitude of a plane flying in the sky?
0 feet
−100 feet
1,200 feet
−500 feet

Explanation:

Step1: Understand altitude concept

Altitude is the height above sea - level. It cannot be negative as it represents a distance above a reference point (sea - level).

Step2: Analyze options

0 feet means the plane is at sea - level, not really flying in the sky. Negative values are not possible for altitude. 1,200 feet is a positive value representing a height above sea - level.

Answer:

1,200 feet
