Answer:
32 years
Explanation:
From the question we have;
- Rate of growth of a tree; 3/8 inches per year
- Current diameter of the tree is 12 inches
We are required to determine the age of the tree;
- To determine the age of the tree we will divide the diameter of the tree by the annual rate of growth.
Age of the tree = 12 inches ÷ 3/8 inches per year
= 32 years
Thus, the tree is 32 years old
