Question

What is the approximate average rate of

Answer 1

Answer:

Average change in height of the plant is 0.5 cm per day.

Step-by-step explanation:

Height of the plant on day 20 = 40 cm

Height of the plant on day 40 = 50 cm

Change in height = 50 - 40 = 10 cm

Number of days between day 20 and day 40 = 20

Average change in height of the plant = $\frac{\text{Change in height of the plant}}{\text{Duration}}$

                                                                = $\frac{10}{20}$

                                                                = 0.5 cm per day

Therefore, average change in height of the plant is 0.5 cm per day.
