Unit 5: Ratios and Proportions (Standards \( 3-5 \) ) 10.) A large jet uses 7,500 gallons of fuel to fly 1,500 miles. What is the unit rate of fuel used by this vehicle? Show your work! Answer: \( \quad 5 \)

To find the unit rate of fuel used by the jet, you divide the total gallons of fuel by the total miles flown. So, you take \( 7,500 \) gallons and divide it by \( 1,500 \) miles: \[ \text{Unit rate} = \frac{7,500 \text{ gallons}}{1,500 \text{ miles}} = 5 \text{ gallons per mile} \] This means the large jet uses \( 5 \) gallons of fuel for every mile it flies. Now think about this in real-world terms: If you're planning a long trip and know your vehicle's fuel efficiency, you can estimate how much fuel you'll need! Also, it's a great way to track costs - just multiply the gallons used by the current price of fuel, and you can predict your expenses for the journey!
