Answer:
22.5 glasses of water
Explanation:
Because 3/4 of 10 is 7.5 and if he drinks that every 2 min you have to multiple 7.5 by 30 because 60/2 is 30 which is the amount of min in an hour. when you multiple, you get 225. you have to divide that many oz by 10 because that is how many oz are in a glass and you get 22.5 glasses.
