Jennifer and her three cousins drove 165 miles to visit their grandmother. Their car got 24 miles per gallon during the trip. They drove at an average rate of 55 miles per hour and the gasoline for the trip cost $8.94. Calculate each of the following and explain in a complete sentence how you solved the problem. If your sentence has a rate, underline it. 1. Gallons of gasoline used 2. Hours of travel 3. Average feet per second 4. Dollars per hour 5. Dollars per passenger 6. Dollars per mile 7. Dollars per gallon 8. Total number of passenger miles * 9. Passenger miles per gallon 10. Dollars per passenger mile 11. Dollars per passenger per hour * A passenger mile represents one passenger traveling 1 mile. Four passengers traveling 1 mile would be 4 passenger miles. Passenger miles occur because the problem multiplied the number of passengers by the number of miles. This idea will later be used in topics in science such as work, which is measured in foot-pounds.
