Final answer:
To calculate the average rate of growth of the plant, find the difference in height between the 16th and 30th days and divide it by the number of days. The average rate of growth is 1.71 cm per day.
Step-by-step explanation:
To calculate the average rate of growth of the plant from the 16th day to the 30th day, we need to find the difference in height between these two days and divide it by the number of days between them.
The height on the 16th day is 59.0 cm and the height on the 30th day is 35.0 cm. So, the difference in height is 59.0 cm - 35.0 cm = 24.0 cm.
The number of days between the 16th day and the 30th day is 30 - 16 = 14 days.
Now, we can calculate the average rate of growth by dividing the difference in height by the number of days: 24.0 cm / 14 days = 1.71 cm per day.
So, the average rate of growth of the plant from the 16th day to the 30th day is 1.71 cm per day.
