An electrician can wire an average of 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?
Answer (2)
4.5 x 10 = 45
4.5 x 2 = 9
9 + 45 = 54
54 + 4.5 = 58.5
1 + 2 + 10 = 13 weeks
13.5 weeks = 3 months
2 months and 4 weeks
The electrician will take approximately 2.72 months to wire 55 houses, as she can wire 4.5 houses each week. This is calculated by first determining the number of weeks needed, which is about 12.22 weeks, and then converting that into months. Dividing 12.22 weeks by 4.5 gives us the final result in months.
