Unformatted text preview: ⋅ You have to make a round trip. ⋅ Assume your average driving speed to and from the gas station is 45 mph. Average speed is equal to total distance traveled divided by the time it took to travel that distance. 3. Identify the concepts and relevant equations that are related to the problem. ⋅ Gallons to Liters: 1 US gallon = 3.7854118 liters ⋅ 1 liters = 0.264172051 US gallons ⋅ Miles to Kilometers: 1 miles = 1.609344 kilometers ⋅ 1 kilometer = 0.621371192 miles ⋅ 1 gallon of gasoline= 27.6 miles ⋅ Speed formula= Distance/Time 4. Identify how the concepts and relevant equations link the information to what you need to find. • Convert $0.90/liter to $/gallons. 1 liters = 0.264172051 US gallons 0.264172051 liters x .90 = 0.237754846 gallons • Convert 8.7 km to miles 1 miles = 1.609344 kilometers 1 kilometer = 0.621371192 miles 8.7 km x 0.621371192 miles= 5.40592937miles...
