This describes an airplane's flight:
A. Takes off from the ground and climbs for 30 minutes
B. Maintains the same elevation for 2 hours
C. Descends back to the ground
Drag a segment to each box to show the shape of the graph of the airplane's elevation
for each interval of time.

The third box, the fourth box, and the second box

Step-by-step explanation:

The first segment that describes Part A is the one that is increasing because based on the information, the airplane climbs, meaning it's going up.

The second segment that describes Part B is the one that is a straight horizontal line, and this is because the airplane is flying at a constant rate, so it will be straight.

The third segment that describes Part C is the one that is decreasing (going down) slowly. This is because the airplane is down descending, which is also means going down.
