Easy question. Good question though

We would use inches.

A gardener measures the height of a plant after 4 weeks to be 9.0 inches. After 6 weeks the height of the plant is 13.5 inches. In this situation, what UNITS would you use to describe the rate of change of the height of the plant?

The appropriate units are millimeters mm and hours h.

$v=s/t$

$v=\frac{(13.5-9)inches}{(6-4)weeks}$

$v= \frac{4.5\ inches}{2\ weeks}\times\frac{25.4 \ mm}{inch}\times\frac{week}{7\times 24\ h}$

$\large v=0.34\frac{mm}{h}$

   !

Most likely you would hear something in the units of    inches per week

Plant grew  (13.5 - 9) inches   in  TWO weeks

4.5 inches/2weeks   =  2.25 inches/week    For the last two weeks

13.5 inches/6weeks = 2.25 inches per week (also) for the entire 6 weeks    2.25 in/wk
