Benben mini consumes about 70 oil at the same speed and 4.7 oil per 100 kilometers. The uniform speed is about 90, and the fuel consumption per 100 kilometers is about 5.3. Uniform speed is about 100, fuel consumption per 100 kilometers is about 5.8, uniform speed is about 120, and fuel consumption per 100 kilometers is about 7.2.

Assuming good road conditions, you have been running at a constant speed about 100, about 5.8 (fuel consumption per 100 kilometers) * 1287.2 (mileage) *5.47 (the price of No.92 gasoline in our city)/100=408.377 yuan. The basic approximation is 4 10 yuan.
