Answer 3

Calculation of Remaining Time

To calculate how much time Alice has left to work on her homework, we need to determine the total amount of time given by the teacher and subtract the time Alice has already worked.

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 out how much time she has left:

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

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