Problem Analysis

The problem states that the person planned to spend 1 3/4 hours on homework and 1 1/6 hours on cleaning the apartment. However, they ended up spending an additional 3/5 hours on these tasks. The question is asking for the total amount of time spent.

Solution

To find the total amount of time spent, we need to add up the time spent on homework, cleaning the apartment, and the additional time.

Let's calculate each part separately:

1. Homework: 1 3/4 hours - To add mixed numbers, we need to convert the mixed number to#### Task Analysis To solve this problem, we need to calculate the total time spent on doing homework and cleaning the apartment, taking into account the additional time spent.

Calculations

Let's start by calculating the time spent on doing homework and cleaning the apartment separately.

1. Time spent on doing homework: - Initially planned time: 1 3/4 hours - Additional time spent: 3/5 hours - Total time spent on doing homework = Initially planned time + Additional time - Total time spent on doing homework = 1 3/4 + 3/5 hours

2. Time spent on cleaning the apartment: - Initially planned time: 1 1/6 hours - Additional time spent: 3/5 hours - Total time spent on cleaning the apartment = Initially planned time + Additional time - Total time spent on cleaning the apartment = 1 1/6 + 3/5 hours

3. Total time spent on both activities: - Total time spent = Total time spent on doing homework + Total time spent on cleaning the apartment

Let's calculate each of these steps.

Calculations

1. Time spent on doing homework: - Initially planned time: 1 3/4 hours - Additional time spent: 3/5 hours - Total time spent on doing homework = 1 3/4 + 3/5 hours - Total time spent on doing homework = 1 3/4 + 3/5 - Total time spent on doing homework = 7/4 + 3/5 - Total time spent on doing homework = (7*5 + 4*3) / (4*5) - Total time spent on doing homework = (35 + 12) / 20 - Total time spent on doing homework = 47 / 20 - Total time spent on doing homework = 2 7/20 hours

2. Time spent on cleaning the apartment: - Initially planned time: 1 1/6 hours - Additional time spent: 3/5 hours - Total time spent on cleaning the apartment = 1 1/6 + 3/5 hours - Total time spent on cleaning the apartment = 1 1/6 + 3/5 - Total time spent on cleaning the apartment = 7/6 + 3/5 - Total time spent on cleaning the apartment = (7*5 + 6*3) / (6*5) - Total time spent on cleaning the apartment = (35 + 18) / 30 - Total time spent on cleaning the apartment = 53 / 30 - Total time spent on cleaning the apartment = 1 23/30 hours

3. Total time spent on both activities: - Total time spent = Total time spent on doing homework + Total time spent on cleaning the apartment - Total time spent = 2 7/20 + 1 23/30 hours - Total time spent = 2 7/20 + 1 23/30 - Total time spent = 2 7/20 + 1 23/30 (finding a common denominator) - Total time spent = 2 21/60 + 1 46/60 - Total time spent = 3 67/60 - Total time spent = 4 7/60 hours

Answer

The total time spent on both activities, including the additional time, is 4 7/60 hours.
