(b) A bothtub can hold 66 gallons of water. The faucet adds 5.5 gallons of water to the bathtub every minute, Find out how many minutes it takes to fill the empty bathtub. a4) Let \( m \) be the number of minutes it takes to fill the bathtub. Write a multiplication equation to describe the situation. \( 60=5.5 \mathrm{~m} \) 4i) How many minutes does it take to fill the bathtub? 4i) It takes \( \square \)

To fill the bathtub, you need to fill it with 66 gallons of water, and since the faucet is pouring in 5.5 gallons per minute, you can set up the equation \( 66 = 5.5m \). Dividing both sides by 5.5 gives you \( m = \frac{66}{5.5} = 12 \). So, it takes 12 minutes to fill the empty bathtub. Isn't it fascinating how something as simple as filling a bathtub can be expressed in numbers? This scenario is a perfect example of proportions in real life. Understanding these concepts can greatly assist in tasks like calculating how long it will take to fill a pool, or even how long to run a shower if you're aiming for a specific water usage!
