Dominik Conley · Answer 1

1) Assuming that 1 month is 30 days. We would take 30 (# of days in the month) divided by 4, which would be 7.5. So every 7.5 days (or 1/4 of a month) she will build 1 1/2 simple machines. so 1 1/2 times 4 equals 6. She will build 6 simple machines each month.

3) D. 6 miles, you would take 60 divided by 6 which is 10, divided by 3/5 which is 6.
