Question

A large pool has a faucet to allow water to enter the pool and a drain to allow water to leave the pool.

Each minute, the faucet allows 1215 gallons of water to enter the pool, and the drain allows 1523 gallons to leave the pool.

What is the change in the amount of water in the pool after 112 minutes?

Answer 1

-34496 gallons = 34496 gallons less

Explanation:

In 112 minutes, 1215(112) = 136080 gallons of water is added by the faucet

In 112 minutes, 1523(112) = 170576 gallons of water are drained from the pool.

So, assuming that the pool is not completely drained in the 112 minute time interval, the change in the amount of water = 136080 - 170576 = -34496 gallons; i.e., the amount of water in the pool is 34496 gallons less.
