It is a Sunday morning, and Kerri saw a leak coming from the water heater in her attic. Since plumbers charge extra to come out on weekends, Kerri is planning to use buckets to catch the dripping water. She places a bucket under the drip and sees in an hour and a half, the bucket is 1/4 of the way full. What is the rate at which the water is leaking per hour? And what is the longest can Kerri be away from the house before the bucket overflows? please help me!
