Step-by-step explanation:

Answer 2

Answer:

The total taken to wash one window of the building is 6 minutes.

The number of windows(n) = 30.

Time taken to wash every window(t) = 3 hours

                                                             = 3 * 60 minutes.

                                                             = 180 minutes.

To calculate the total minutes taken to wash each window we have to divide the total time taken in minutes by the number of windows. So,

Time taken to wash 1 window = Total time taken/ number of windows

                                                  = 180 minutes/30

                                                  = 6minutes.

Therefore, the total time taken to wash one window =  60 minutes.
