In the US a typical family car covers 120,000 miles over its life and delivers, on average 25 miles per US gallon (6.6 miles per liter). Petrol in the US costs $ 0.63 per liter, so the life cost for fuel is $11,455. The typical family car, when loaded, weighs 2315 kg. If the petrol consumption is directly proportional to the weight, what is the value of reducing the weight of the car by 1 kg
