In one day, Peter cleaned 17.5 rooms in 8.75 hours while working for a house cleaning business. Approximately how many rooms did he clean per hour?

Question

2 rooms
5 rooms
8 rooms
9 rooms

Answer 1

To find out how many rooms Peter cleaned per hour, you can divide the total number of rooms cleaned by the total hours worked.

Peter cleaned 17.5 rooms in 8.75 hours.

\[ \text{Rooms per hour} = \frac{\text{Total Rooms}}{\text{Total Hours}} = \frac{17.5 \text{ rooms}}{8.75 \text{ hours}} = 2 \text{ rooms per hour} \]

So, Peter cleaned approximately 2 rooms per hour.
