Answer:
0.42 cm/hour
Explanation:
We can find the average change by dividing change in height by the number of hours.
First Calculate the change in height of the seeds:
change in height = 13.6 cm - 11.1 cm = 2.5 cm
Than
Calculate the average change in height per hour:
average change in height per hour = change in height / number of hours
average change in height per hour = 2.5 cm / 6 hours = 0.42 cm/hour
Therefore, the average change in the height of the seeds each hour is approximately 0.42 cm/hour.
