Nolan is filling a small kiddie pool that is 18 inches deep. He notices that it takes two minutes to fill the pool with three inches of water. How many minutes will it take Nolan to fill the pool if it continues at the same rate
3 inches every 2 minutes, divide the 3 by 18 since the pool is that many inches deep and multiply 6 by 2 since it fills 3 more inches every 2 minutes and thats your answer.
