claudia went on a skydiving adventure. she jumped when the plane was at an altitude of 10,000 feet and landed safely on the gound at sea level. whhich integer best represent claudia's elevation in feet when she landed?
a. -10,000
b. 0
c. 5,000
d. 10,000
She was 10,000 feet above the ground. When she came back to ground, or sea level, she is not at any elevation. So it is B.
I thought that - but it seemed too logical of an answer. Thanks.
To solve this problem, we need to determine the change in Claudia's elevation from the plane to the ground.
We know that the plane was at an altitude of 10,000 feet, and she landed at sea level. Sea level is typically considered to be at an elevation of 0 feet.
To determine Claudia's elevation when she landed, we need to calculate the change in elevation.
Elevation change = Landing elevation - Takeoff elevation
In this case, the landing elevation is 0 feet, and the takeoff elevation is 10,000 feet.
Elevation change = 0 - 10,000 = -10,000 feet
Therefore, the best integer that represents Claudia's elevation in feet when she landed is -10,000 feet.
So, the correct answer is (a) -10,000.
