if your 3 room attendant clean rooms in 35,42 and 55 minutes what is the mean (average) time for them to clean room?

Answer 1

To find the mean (average) time for the room attendants to clean the rooms, you can add the times together and then divide by the number of attendants.

The cleaning times are:

• 35 minutes
• 42 minutes
• 55 minutes

First, add these times together: \[ 35 + 42 + 55 = 132 \text{ minutes} \]

Next, divide the total time by the number of attendants (which is 3): \[ \text{Mean} = \frac{132 \text{ minutes}}{3} = 44 \text{ minutes} \]

So, the mean (average) time for the room attendants to clean a room is 44 minutes.
