Question

A tree grows to a height of 32.4 metres over period of $$ 8 \frac{1}{2} $$ years. What is the average annual growth rate in metres per year?

UpStudy AI · Accepted Answer

To find the **average annual growth rate** of the tree, you can use the formula:

$$
\text{Average Annual Growth Rate} = \frac{\text{Total Height Grown}}{\text{Total Time Period}}
$$

Given:
- **Total Height Grown** = 32.4 meters
- **Total Time Period** = $$ 8 \frac{1}{2} $$ years = 8.5 years

Plugging in the values:

$$
\text{Average Annual Growth Rate} = \frac{32.4 \text{ meters}}{8.5 \text{ years}} \approx 3.82 \text{ meters per year}
$$

**Answer:**  
The tree grows on average 3.82 meters per year.
The tree grows an average of 3.82 meters each year.
