Question

Jaz was 43 inches tall. Eighteen months later she was 52 inches tall. Find the constant rate of change for jazz height

Answer 1

52 - 43 = 9 inches

9/18 = .5

.5 inches a month

Answer 2

Constant rate of change for Jaz height will be 0.5 inch per month

Explanation:

Jaz present height is 43 inches.

Eighteen months later her height will be 52 inches.

Now we know rate of change will be represented by the formula

Rate of change of height =
`\frac{\text{Change in height}}{\text{Duration of the change in height}}`

=
`(52-43)/(18)=(9)/(18)`

= 0.5 inch per month

The constant rate of change for Jaz height will be 0.5 inch per month.
