If it takes 20 seconds for a machine to fill three water bottles, how many bottles will it fill in 3 minutes? a) 21 b) 18 c) 28 d) 27 e) 15 (i) Message

In 20 seconds, the machine fills three bottles, which means it fills 0.15 bottles per second (3 bottles / 20 seconds). With 3 minutes being 180 seconds, you can multiply that rate: 0.15 bottles x 180 seconds = 27 bottles. So, the answer is d) 27! Now, if you're ever stumped by similar problems or math word problems, remember that breaking them down into smaller parts can help immensely. Just like decomposing a complex dish recipe into simpler steps, you can clarify what you need to find and how to get there. Also, remember to check your work as you go. It's easy to lose track of your calculations, especially under time pressure. Double-checking allows you to catch little errors before they add up! Happy calculating!
