Which situation is most likely to have a constant rate of change? a. length of a bead necklace compared with the number of identical beads b. distance a school bus travels compared with the number of stops c. number of trees in a park compared with the area of the park d. number of runs scored in a baseball game compared with the number of innings

A. Length of a bead necklace compared with the number of identical beads

Step-by-step explanation:

A. Length of bead necklace increases simultaneously compared with the increases in number of identical beads . This is a proportional relationship .

So, There is constant rate of change which is equals to the length of each bead.

B. Distance a school bus travels compared with the number of stops .

There is no constant rate of change between the quantities .[The time when bus stops matter]

C.Number of trees in a park compared with the area of the park.

There can be free space ,so there is not proportional relationship .

D.Number of runs scored in a baseball game compared with the number of innings

Not proportional relationship.
