The half-life of caffeine is 5 hours. If you ingested a 30 oz Big Gulp, after how much time will have to pass before you have under 1 oz of caffeine remaining?

The time that will have to pass before one has under 1 oz of caffeine remaining is 24.53 hours

Explanation:

Here, we have the formula for half life as follows;

Where:

N(t) = Remaining quantity of the substance = 1 oz

N₀ = Initial quantity of the substance = 30 oz

t = Time duration

= Half life of the substance = 5 hours

Therefore, plugging in the values, we have

The time that will have to pass before one has under 1 oz of caffeine remaining = 24.53 hours.
