Answer 3

Calculation of Remaining Time for Alice's Homework

To calculate the remaining time for Alice to work on her homework, we need to determine the total time given to her and subtract the time she has already worked.

Given information: - Alice was given 15 minutes to complete her homework. - She has already worked for 30 minutes.

To find the remaining time, we can subtract the time already worked from the total time given:

Remaining time = Total time given - Time already worked

Substituting the given values:

Remaining time = 15 minutes - 30 minutes

Now let's calculate the remaining time:

Remaining time = -15 minutes

Based on the calculation, the remaining time is -15 minutes. However, this result doesn't make sense because it implies that Alice has exceeded the time given to her. It's important to note that the remaining time cannot be negative.

Therefore, we can conclude that Alice has already exceeded the time given to her by 15 minutes.

Please note that the given question doesn't provide enough information to determine the exact remaining time. If you have any additional information or if there is any specific context missing, please let me know, and I'll be happy to assist you further.
