Final answer:
Maurice's average washing time per house is 45 minutes, which is found by converting the total washing time to minutes and dividing by the number of houses washed.
Step-by-step explanation:
The question asks to calculate the average washing time Maurice takes to power wash a house on his house washing service. Maurice washed 5 small houses in a total of 3 hours and 45 minutes. To find the average time he spent per house, the total time needs to be divided by the number of houses.
Firstly, convert the hours into minutes:
- 3 hours × 60 minutes/hour = 180 minutes
- 180 minutes + 45 minutes = 225 minutes in total
Next, divide this total time by the number of houses washed:
- 225 minutes ÷ 5 houses = 45 minutes/house
So, Maurice's average washing time per house is 45 minutes.
