Final answer:
Adrian's car uses gas at a rate of 304 miles per gallon, calculated by dividing the number of miles traveled (38 miles) by the fraction of a gallon used (1/8 gallon).
Step-by-step explanation:
To calculate the rate at which Adrian's car uses gas in miles per gallon, we need to divide the number of miles traveled by the amount of gasoline used.
Adrian's car traveled 38 miles using of a gallon of gasoline. Assuming the typo 'ƒ' was intended to represent '1/8', we would have the following calculation:
- Calculate miles per gallon (mpg): mpg = Total Miles Travelled / Gallons of Gas Used
- Plug in the known values: mpg = 38 miles / (1/8 gallon)
- Simplify the equation: mpg = 38 miles * (8/1)
- Complete the calculation: mpg = 38 * 8 = 304 miles per gallon
Therefore, Adrian's car uses gas at a rate of 304 miles per gallon.
