Question

Ethan planted a tree that is 37.5 inches tall.if the tree grows 3 inches each year, how long will it take for the tree to reach a hieght of 54 inches?

Answer 1

Answer: 5.5

Explanation:

The current height of the tree = 37.5 inches.

The tree needs to grow by 54 - 37.5 = 16.5

We know the rate of the growth to be: 3 inches in 1 year

So for,

16.5 inches = x years

x = 1 x 16.5 / 3

x = 5.5 years

Answer 2

First find out how many more inches it needs to grow, 54-37.5; It needs to grow 16.5 more inches. If it grows 3 inches a year then you have to do 16.5/3; 5.5. It will take 5.5 or 5 1/2 more years to grow to 54 inches.
