Question

Vivian is at a fair in Coachella Valley, California. Much of the valley lies below sea level. Vivian has brought along an altimeter to measure her elevation at different places in the valley. Vivian’s first ride was on the Ferris wheel. When she sat on the wheel at its lowest point, her altimeter read -9.6 feet. When she reached the top of the wheel, her altimeter read 12.3 feet.

Is the change in Vivian's elevation from the bottom of the Ferris wheel to the top a positive number or a negative number? Why?

Answer 1

Answer: Its a positive number

If you look it says she is at sea level which is 0 and she is going up 12.3 feet so its positive.

Answer 2

It is a positive because 12.3 is going to overflow -9.6 therefore you answer is going to positive.
