Final answer:
The maximum distance you can travel with a full 15-gallon tank, when your truck consumes 0.25 gallons per mile, is 60 miles (option C).
Step-by-step explanation:
To calculate the maximum distance you can travel on a full tank of gas, you can use the formula:
Distance = Number of gallons × Miles per gallon
In your case, you have 15 gallons of gas and your truck consumes 0.25 gallons per mile. This means that the truck gets 4 miles per gallon (since 1 gallon takes you 4 miles). Therefore, to find the maximum distance:
Distance = 15 gallons × 4 miles/gallon = 60 miles
So, with a full tank of 15 gallons, the maximum distance you can travel is 60 miles, which corresponds to option C).
