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

How do you calculate the number of gallons needed for the trip?

• Divide miles by gallons per mile

• Multiply miles by gallons per mile

• Divide miles by miles per gallon

• Multiply miles by miles per gallon

What is the reciprocal of 25 miles per gallon?

• 1/25 miles per gallon

• 25 gallons per mile

• 25 miles per gallon

• 1/25 gallons per mile

Why is it important to perform a reality check after calculating the gallons needed?

• To find the cheapest gas station

• To check the weather conditions

• To ensure the calculation is correct

• To determine the fastest route

What is the calculated number of gallons needed for the trip?

• 25 gallons

• 16 gallons

• 400 gallons

• 3 gallons

How do you calculate the total cost of the trip?

• Multiply the number of gallons by the cost per gallon

• Add the number of gallons to the cost per gallon

• Divide the number of gallons by the cost per gallon

• Subtract the number of gallons from the cost per gallon

What is the cost per gallon of gas in the problem?

• $4

• $3

• $2

• $5

What is the total cost of the road trip?

• $25

• $100

• $75

• $48

What happens to the units when calculating the total cost?

• Miles cancel out with gallons

• Gallons cancel out with dollars

• Gallons cancel out with gallons

• Dollars cancel out with miles

What is the final step in confirming the total cost of the trip?

• Recheck the fuel efficiency

• Divide the gallons by the cost per gallon

• Recalculate the distance

• Multiply the gallons by the cost per gallon
