Two automobile manufacturers designed a car that runs on gasoline stored in a tank near the engine, which is located at the rear of the vehicle. Company A offers the car at $20,000 and it speeds up to 140 km per hour and can travel 18 km per liter of fuel. The car from company B costs $16,000 and averages 16 km per liter of gasoline. If the fuel costs $1.2 per liter and MARR is 10% per year, over what range of annual kilometres driven is company A's car more economical? Assume a useful life of 5 years for both cars.
