Question

All of the machines are kept cool be circulating cold water through them. The water makes one complete cycle through a 30-foot long tube every 12 seconds. Correctly complete the statement about the distance traveled by the water in 3 minutes and the number of cycles the water makes in two minutes.

Answer 1

It will travel 450ft in 3 minutes and it will make 10 cycles in 2 min.

Explanation:

divide 60 by 12 to see how many cycles it takes in one minute; the answer is 5. Multiply 3 times 5 to see how many cycles it will take in 3 minutes; the answer is 15. Then do 15 times 30 because it will go 30 feet 15 times; the answer is 450ft.

the water makes 5 cycles per minutes. Multiply 5 time 2 because we need to know how many cycles it will take in 2 minutes; the answer is 10.
