Answer :
Final answer:
The unit rate is calculated by dividing the total distance traveled (100.5 miles) by the total gallons of gasoline used (3.75 gallons). The result, when rounded to the nearest decimal place, gives us the unit rate in miles per gallon.
Explanation:
To calculate the unit rate as a decimal, we need to divide the number of miles (100.5) by the number of gallons (3.75). The division operation is the approach used to determine the unit rate in such situations. The unit rate is often used to compare different quantities and their relationship. In this case, it is the relationship between miles and gallons.
In mathematical steps:
- Step 1: Identify the total mileage covered (100.5 miles).
- Step 2: Identify the total gallons of gasoline used (3.75 gallons).
- Step 3: Divide the total mileage by the total gallons of gasoline used (100.5 miles divided by 3.75 gallons).
- Step 4: The quotient, when rounded to the nearest two decimal places, is the unit rate in decimal form. So the unit rate of the car is 26.8 miles per gallon.
