Explanation:

In the span of 6 hours, the height of the seeds changed from 13.6cm to 11.1cm, which is a decrease of 2.5cm.

Average change in height = -2.5cm/6 ≈ -0.42cm/hr.

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.
