From the information given,
santa drinks one and a 1/2 cup of a 6 oz glass of water in a 2/3 of an hour.
Let x represent the number of cups of 6 oz glass of water that santa drinks in an hour.
Therefore,
1.5 cup = 2/3 hour
x cups = 1 hour
By cross multiplying, it becomes
1 * 1.5 = 2/3 * x
2x/3 = 1.5
2x = 3 * 1.5 = 4.5
x = 4.5/2
x = 2.25
She drinks 2.25 cups of a 6 oz glass of water in 1 hourof a 6 oz
