Y, wasss good, Im bored anyone down to talk? ima guy, 15 yrs olds btw. :)

Which of those sequences is a geometric sequence

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?

Anyone? 15m is what percent of 60m; 3m; 30m; 1.5 km?
