Time taken to do the homework

To find out how long Morena took to do her homework, we need to subtract the starting time from the finishing time.

Step 1: Convert the starting and finishing time to a common format
Morena started her homework at 7.20 p.m. This can be written as 7:20 p.m.
She finished her homework at 8.05 p.m. This can be written as 8:05 p.m.

Step 2: Calculate the time difference between the starting and finishing time
To find the time difference, we subtract the starting time from the finishing time.

8:05 p.m. - 7:20 p.m. = 45 minutes

Therefore, Morena took 45 minutes to do her homework.

Answer: (b) 45 min
