Question

Victoria's car used of a gallon to travel 21 miles. At what rate doesthe car use gas, in miles per gallon?

Answer 1

The rate doesthe car use gas, in miles per gallon is 26 1/4 miles per gallon

How can the rate be determined?

A rate is a ratio used to compare two distinct numbers with various unit systems. John's typing pace, for instance, would be 50 words per minute if he were to type 50 words in a minute. The fact that the word "per" indicates that we are working with a rate.

Based on the provided information about the the car it can be deduced that the car travels 21 miles per 4/5 gallons and here the rate at which the car uses the gas ccan be expressed as;

Rate =21 miles /4/5 gallons

=(21*5)/4

=105/4

=26 1/4 miles per gallon

Answer 2

26 1/4 miles per gallon

Explanation:

We are told that the car travels 21 miles per 4/5 gallons. Therefore, the rate at which the car uses the gas is

`\frac{21\text{ miles}}{4/5\text{ miles}}`

which can also be written as (by taking the reciprocal of the denominator)
