5 Soccer training starts at \( 3: 45 \mathrm{pm} \). 5.1 Convert the time to 24-hour format

To convert the time \( 3:45 \mathrm{pm} \) to 24-hour format, we follow these steps: 1. **Identify the hour**: In 12-hour format, \( 3:45 \mathrm{pm} \) means it is in the afternoon. 2. **Add 12 to the hour**: For any time in the afternoon (from \( 1:00 \mathrm{pm} \) to \( 11:59 \mathrm{pm} \)), we add 12 to the hour. So, \( 3 + 12 = 15 \). 3. **Keep the minutes the same**: The minutes remain unchanged. Thus, \( 3:45 \mathrm{pm} \) in 24-hour format is \( 15:45 \).
