Answer:
The new ratio is 30 miles : 1 gallon it called the unit rate
Step-by-step explanation:
* Lets explain what is the unit rate
- A unit rate describes how many units of the first type of quantity
equal to one unit of the second type of quantity
- Ex: 3 miles per hour
$100 per day
15 students per class
- A unit rate is a rate with 1 in the denominator
- Ex: $20 for 5 pens, the rate is 20 : 5 divide the two terms by the
denominator 5, then 20 : 5 = 4 : 1 then unit rate is $4 per pen
* Lets solve the problem
- A car can travel 300 miles on 10 gallons of gas
∴ The rate is 300 miles per 10 gallons
- To find the unit rate divide the two terms of the rate by 10
∴ 300 : 10 = 300/10 : 10/10
∴ 300 : 10 = 30 : 1
∴ The unit rate is 30 miles per gallon
* The new ratio is 30 miles : 1 gallon it called the unit rate
