Question

A tree measured 25 1/2 feet tall. Over the next 7 1/2 years, it grew to be 63 feet tall. During the 7 1/2 years, what was the average yearly growth rate of the tree?

Answer 1

Greetings!

Answer:

5feet per year

Explanation:

We need to find the distance it grew in that 7 1/2 years:

63 - 25 1/2 = 37 1/2

Now to find the average yearly growth we can divide this by 7 1/2:

37.5 ÷ 7.5 = 5

So the yearly rate of growth of the tree is 5f/y

Hope this helps!
