Question

grass clippings are found to have an average length of 6.4 cm when a lawn is mowed 26 days after the previous mowing. what is the average speed of growth of this grass in cm/day? the average speed of growth of the grass is \boxed{} cm/day.

Explanation:

Step1: Define growth speed formula

Average growth speed = $\frac{\text{Total grown length}}{\text{Total time}}$

Step2: Substitute given values

Average growth speed = $\frac{6.4}{26}$

Step3: Calculate the result

$\frac{6.4}{26} \approx 0.25$

Answer:

0.25 cm/day
