An electrician can wire on 4.5 houses in a week. How many months will it take her to wire 55 houses if she wires the same number each week and figures on 4.5 weeks per month

I believe the answer is 2 months and 4 weeks ... at 2months and 3 weeks however she has wired 54 houses. so you need to add another week because at 2 months and 3 weeks you havent reached 55 houses yet.
