Question

A ratio that compares two quantities with different kinds of units iscalled a rate. When a rate is simplified so that it has a denominator of 1unit, it is called a unit rate.Ex 1. Find each unit ratea.$156 for 3 booksb.250 miles in 4 hours

Answer 1

To find the unit rate, all we have to do is calculate the actual division. On the first item we have "$156 for 3 books".

This rate tells us the price every 3 books we buy. The unit rate would be the price of 1 book.

`(156)/(3)=52`

We have a unit rate of $52/book.

In the second item, we have "250 miles in 4 hours"

`(250)/(4)=62.5`

We have a unit rate of 62.5 miles/h.
