On average, Jeriel drinks four fiths of a 6-ounce glass of water in 5 minutes. How much water does he drink, in glasses per hour?

To find out how much water Jeriel drinks in 5 minutes, we need to first calculate how much water is in four fifths of a 6-ounce glass.

Four fifths of 6 ounces is:
4/5 * 6 = 4.8 ounces

Now, we need to convert this to how much water Jeriel drinks in an hour. There are 12 five-minute intervals in an hour.

So, Jeriel drinks:
4.8 ounces * 12 = 57.6 ounces

Since there are 6 ounces in a glass of water, Jeriel drinks:
57.6 / 6 = 9.6 glasses of water per hour

Therefore, Jeriel drinks 9.6 glasses of water per hour.
