Question

A tree grow 1 & 3/4 feet per year. How long will it take the tree to grow from a height of 21 & 1/4 feet to a height of 37 feet?

Answer 1

9 Years

Explanation:

Start by finding the difference between the starting height and the ending height. This will tell you how far the tree has to grow (I'm going to replace fractions with decimals):
`37-21.25=15.75`
Then you divide the difference by the amount of rate the tree grows every year (1.75 feet/year).
`15.75/1.75=9`
This leaves you with the number of years taken for the tree to grow to this height.
