Suppose 4.5 liters of water come out of a faucet each minute for how many minutes was the faucet on if 48.6 liters of water came out

Question

Suppose 4.5 liters of water come out of a faucet each minute for how many minutes was the faucet on if 48.6 liters of water came out

Answer 1

This is a kind of rate problem.  In general, rate x time = amount.

 

But you can also say, amount / rate = time.

 

So the amount is 48.6 liters and the rate is 4.5 liters per minute.

 

So the time the faucet was on was 48.6 / 4.5 = 10.8 minutes.
