It is saturday morning and jeremy has discovered he has a leak coming from the water heater in his attic. since plumbers charge extra to come out on the weekends, jeremy is planning to use buckets to catch the dripping water. he places a bucket under the drip and steps outside to walk the dog. in half an hour the bucket is 1/5 of the way full. what is the rate at which the water is leaking per hour?

Having a hard time understanding this question (see attachment).

An elevator travels 310 feet in 10 seconds. at that speed, how far can't his elevator travel in 12 seconds?
