Question

If you are assigned 30 rooms to clean and you have 7 hours to complete all 30 rooms, how much time should you allow for each room?

Answer 1

7 hours x 60 minutes = 420 minutes
420 minutes / 30 rooms = 14 minutes per room

Answer 2

Time taken to clean 30 rooms = 7 hours

Since, 1 hour = 60 minutes

Therefore, 7 hours = $7 \times 60$ = 420 minutes

Time taken to clean 30 rooms = 420 minutes

Time taken to clean 1 room = $\frac{420}{30}$

= 14 minutes.

Therefore, it will take 14 minutes to clean each room.
