Question

An animal gained 5 kilograms steadily over 20 years. What is the unit rate of kilograms per​ year?

Answer 1

The unit rate is 0.25 kilograms per year.

Step-by-step explanation:

Lets define unit rate first

Unit rate is the change in quantity per unit time.

Given

Weight = w = 5 kg

Time = t  = 20 years

So,

$Unit\ rate = \frac{weight}{time}\\=\frac{w}{t}\\= \frac{5}{20}\\= 0.25$

Hence,

The unit rate is 0.25 kilograms per year.
