It takes Bonnie 18 minutes to vacuum
2 rooms. Assuming the rooms are the
same size and Bonnie works at the same
speed, about how long will it take her to
vacuum 4 rooms?


Answer :

Answer:

36 min

Step-by-step explanation: 18 divided by 2 is 9. so 9x 4 is 36

18/2 = 9 per room
9*4 = 36 minutes for 4 rooms
