Calculation of Alesha's Study Time

To determine at what time Alesha started studying, we need to calculate the total time he spent eating and resting, as well as the time he spent walking.

Let's break down the given information:

- Alesha spends 50 minutes eating and resting. - After that, he spends 1.5 hours (or 90 minutes) walking.

To find out when Alesha started studying, we need to add the time he spent eating and resting to the time he spent walking, and then subtract that total from the time he returned home from school.

Let's calculate it step by step:

1. Convert the time Alesha spent eating and resting from minutes to hours: 50 minutes ÷ 60 minutes/hour = 0.83 hours.

2. Add the time Alesha spent eating and resting to the time he spent walking: 0.83 hours + 1.5 hours = 2.33 hours.

3. Subtract the total time (2.33 hours) from the time Alesha returned home from school (14:45):

- Convert 14:45 to hours: 14 hours + 45 minutes ÷ 60 minutes/hour = 14.75 hours.

- Subtract 2.33 hours from 14.75 hours: 14.75 hours - 2.33 hours = 12.42 hours.

Therefore, Alesha started studying at approximately 12:25 PM.

Please note that the given information does not specify the duration of Alesha's study time, so we can only determine when he started studying based on the provided information.
