A bathtub can hold 66 gallons of water. The faucet adds 5.5 gallons of water to the bathtub every minute. find out how many minute it takes to fill the empty bathtub.

Let m be the number of minute it takes to fill the bathtub. Write a multiplication equation describe the situation.
66=5.5m
How many minute does it take to fill the bathtub?
it takes ? minutes to fill the bathtub.

To solve for m, we divide both sides of the equation by 5.5:

66 = 5.5m
m = 66 / 5.5
m = 12

Therefore, it takes 12 minutes to fill the empty bathtub.
