A tree initially measured 38 1/2 feet tall. Over the next 5 1/2 years, it grew to a final height of 49 1/2 feet. During those 5 1/2 years, what was the average yearly growth rate of the height of the tree?

2feets per year

Step-by-step explanation:

49,5-38,5=11feets --->this is how much it grew in 5,5years

11/5,5=2feets/year --->this is the yearly rate
