The half life of caffeine in a healthy adult is 5.7 hours. jeremiah drinks 16 ounces of caffeinated coffee in the morning. how long will it take for only 40% of the caffeine to remain in his body?

around 3.5 hours

Step-by-step explanation:

The correct answer 7.5 hours.

Step-by-step explanation:

In this case, half life refers to the time that is necessary for a quantity to reduce to half of its original value. In this case, the half-life of caffeine is 5.7 hours, meaning that if we had 10 ounces of it, the remaining after this time would be 5 ounces.

In the question, the initial amount is 16 ounces, so it will take 7.5 hours of the caffeine to remain in his body.
