Q. Roselyn is driving to visit her family, who live 150 kilometers away. Her average speed is 60 kilometers per hour. The car's tank has 20 liters of fuel at the beginning of the drive, and its fuel efficiency is 6 kilometers per liter. Fuel costs 0.60 dollars per liter.What is the price for the amount of fuel that Roselyn will use for the entire drive?__________dollars
Calculate total distance and fuel efficiency: Calculate the total distance Roselyn will drive and the fuel efficiency to find out how much fuel she will need.Total distance = 150 kilometers, Fuel efficiency = 6 kilometers per liter.Fuel needed = Total distance / Fuel efficiency = 150km/6km per liter=25liters.
Calculate fuel cost: Calculate the cost of the fuel used for the drive.Fuel cost per liter = 0.60 dollars.Total fuel cost = Fuel needed × Fuel cost per liter = 25 liters ×0.60 dollars/liter = 15 dollars.
