Suppose 48.6 liters of water came out of a faucet today. If 4.5 liters of water come out each minute, for how many minutes was the faucet on?

Answers

4.5*x=48.6  

48.6-4.5=44.1

4.5x11=49.5-44.1=45.4+3.2=48.6

so it was on for 11 min

Final answer:

The faucet was turned on for approximately 10.8 minutes.

Explanation:

This problem pertains to the division operation in mathematics. Given that 48.6 liters of water came out of the faucet and that 4.5 liters come out each minute, we can find the time the faucet was on by simply dividing the total volume by the volume per minute: 48.6 liters / 4.5 liters per minute which equals approximately 10.8 minutes. Therefore, the faucet was on for approximately 10.8 minutes.
