Answer 3

Calculation of Remaining Time

To calculate the remaining time for Alice to work on her homework, we need to determine how much time she has already worked and how much time was initially given to her by her teacher.

Given that 15 minutes is 1/4 of the total time given by the teacher, we can calculate the total time as follows:

Total time = 15 minutes * 4 = 60 minutes

Since Alice has already worked for half an hour (30 minutes), we can subtract this from the total time to find the remaining time:

Remaining time = Total time - Time already worked = 60 minutes - 30 minutes = 30 minutes

Therefore, Alice has 30 minutes remaining to work on her homework.
