Vavilen inflated a huge balloon in 191919 minutes. Then he poked a hole in the balloon so that it slowly leaked air out until it was completely deflated.
The rate at which the air leaked out of the balloon (in liters of air per minute) was half of the rate at which Vavilen inflated the balloon. It took the balloon 383838 minutes to completely deflate.
At what rate did Vavilen inflate the balloon, and at what rate did the balloon deflate?

Choose 1 answer:

A) There is not enough information to determine exactly how fast Vavilen inflated the balloon or how fast the balloon deflated.

B) The given information describes an impossible situation.

C) Vavilen inflated the balloon at the rate of 3.83.83, point, 8 liters per minute, and the balloon deflated at the rate of 1.91.91, point, 9 liters per minute.

D) Vavilen inflated the balloon at the rate of 1.91.91, point, 9 liters per minute, and the balloon deflated at the rate of 3.83.83, point, 8 liters per minute.

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?
