At 4:00 in the afternoon you notice that the kitchen sink is leaking. Unfortunately, you won't be able to repair it until 3:30 PM
the next day. Your sister decides to put an empty cup under the leak to determine
how fast it is dripping so that she can tell you how much water is going to be
wasted if you wait until tomorrow to fix it. After 1.5 hours she has collected a
total of 1/3 cup of water. How much water does she tell you is going to be wasted?
Plz help
