Question

Which situation is most likely to have a constant rate of change?

A. Ounces of water consumed compared with the number of same-size bottles drunk

B. Number of fish in a pond compared with the volume of the pond

C. Points scored in a football game compared with the number of quarters played

D. Distance an airplane travels compared with the number of airports it visits

Answer 1

Answer: A

Step-by-step explanation: A P E X

Answer 2

Answer: A. Ounces of water consumed compared with the number of same-size bottles drunk

Explanation:

When a quantity changes uniformly with respect to the change of other quantity, then we say there is a constant rate of change.

Thus, if one quantity is directly proportional to the other quantity then there is constant rate of change.

A. Ounces of water consumed is directly proportional to the number of same-size bottles drunk. Hence there is a constant rate of change of ounces water with respect to the number of same-sized bottles.

Rest of other options do not have directly proportionality relation between the quantities.
