# Math Help - Average rate of change

1. ## Average rate of change

A protein disintegrates into amino acids according to the formula
M=20/ t+2
where M, the mass of the protein, is measured in grams and t is time measured in hours. Find the average rate of change in mass from t = 0 to t = 3 hours

2. average rate of change of M over the 3 hr period ...

$\frac{M(3)-M(0)}{3-0}$

3. Too late. The above solution is better.

Hope it helps.
