The biological half-life of aspirin is \approx imately 3-4 hours in healthy adults. This means that after this amount of time, half of the ingested dose of aspirin will have been metabolized and eliminated from the body.
It's important to note that the biological half-life of aspirin can vary depending on factors such as age, weight, liver and kidney function, and other medications that may be taken concurrently.
