Question

A tree that grows 3 feet every 5 years is growing at a rate of ___ feet per year. A.0.6 B.15 C.60

Answer 1

A.0.6
0.6*5yrs=3feet a year

Answer 2

The correct option is A. 0.6

Explanation:

Given,

Growth of the tree in 5 years = 3 feet,

So, the growth in 1 year =
`(1)/(5)` × Growth of the tree in 5 years

`=(1)/(5)* 3`

`=0.6\text{ feet}`

Hence, the rate of growing the tree is 0.6 feet per year.

i.e. OPTION A is correct.
