It will take 3 months to wire 55 houses. She can wire 18 a month at 4.5 pee week. So you that's roughly 18 a month. 18x3=54 if there is 4 weeks in a month. If you have 5 weeks in the month then it will bend 22 a month. 22x2.5=55 so in this case just 2 and a half months to wire 55 houses at 4.5 houses a week.
