Question

A cup of coffee contains approximately 95 mg of caffeine. If caffeine is eliminated from the body at a rate of 11% per hour, how long will it take for half of the caffeine to be eliminated from a person’s body?

Answer 1

The half-life of caffeine in the body can be calculated using the formula: half-life = ln(2) / elimination rate.

Plugging in the elimination rate of 11%, we get:
half-life = ln(2) / 0.11 = 6.3 hours

So it will take approximately 6.3 hours for half of the 95 mg of caffeine to be eliminated from a person's body.
