Answer 1

A hotel maid who takes a 15-minute break after cleaning 3 rooms will clean 4 rooms in an hour.

Step-by-step explanation:

The student's question asks how many rooms a hotel maid will clean in an hour if she takes a 15-minute break after cleaning 3 rooms. To solve this, we calculate the total time spent on cleaning within an hour and divide it by the time it takes to clean each room. An hour has 60 minutes, and if we subtract the 15-minute break, the maid has 45 minutes left to clean. If 3 rooms are cleaned in the 45-minute working slot, we can find out the time it takes to clean one room by dividing 45 minutes by 3, resulting in 15 minutes per room. Therefore, in 60 minutes, the maid can clean 4 rooms, since every room takes 15 minutes and the maid works for 45 minutes out of the hour.
