Calculating Trip Costs and Fuel

The video tutorial explains how to calculate the cost of a 400-mile road trip given a car's fuel efficiency of 25 miles per gallon and a gas price of $3 per gallon. It walks through the process of determining the number of gallons needed by converting miles per gallon to gallons per mile, performing a reality check to ensure the calculation is reasonable, and finally calculating the total cost by multiplying the gallons needed by the price per gallon.

What is the main goal of the problem presented in the video?

• To calculate the total distance of a road trip

• To find the best route for a road trip

• To determine the cost of gas for a road trip

• To estimate the time needed for a road trip
