The blood content of an adult weighing 180 kg is about 7200 ml, while the quality of wine is 12000 mg. After drinking, the blood content of the body is12000/72 = 500/3 mg/100 ml.

The minimum standard for drunk driving is 2mg/ 100ml, and 500/3-2 = 494/3mg/ 100ml needs to be removed.

Time of elimination (494/3)/(100 * 90) = 0.0183 hours = 1. 1 minute. That is, I can drive after drinking a bottle of beer for more than 1. 1 minute.
