Final answer:
To convert 192 miles per 12 gallons to a unit rate per quart, multiply the gallons by 4 to find the total quarts. Then divide the miles by quarts to get 4 miles per quart.
Step-by-step explanation:
To write "192 miles on 12 gallons" as a unit rate per quart in simplest form, we need to first convert gallons to quarts. Since 1 gallon equals 4 quarts, we can calculate the total number of quarts by multiplying the number of gallons by 4. In this case:
12 gallons × 4 quarts/gallon = 48 quarts
Now, to find the number of miles per quart, we divide the total number of miles by the total number of quarts:
192 miles ÷ 48 quarts = 4 miles per quart
Therefore, the unit rate of miles to quarts is 4 miles per quart, which corresponds to option (c).
