### Problem 13: Finding the Time the Assembly Ends
Let's solve the problem step by step:
1. Identify the start time of the assembly:
The assembly starts at 7:45 AM.
2. Determine the duration of the assembly:
The assembly lasts for 25 minutes.
3. Add the duration to the start time:
To find the time when the assembly ends, we need to add 25 minutes to 7:45 AM.
- First, add 25 minutes to the 45 minutes part:
45 minutes + 25 minutes = 70 minutes.
- Note that 70 minutes is equal to 1 hour and 10 minutes. So, increment the hour by 1 and convert the minutes:
60 minutes make 1 hour, so:
70 minutes - 60 minutes = 10 minutes
And adding an hour to 7:45 AM would bring us to 8:10 AM.
4. Conclusion:
The assembly ends at 8:10 AM, which is when the students start their lessons.
### Problem 14: Determining the Athlete's Race Time
1. Understand the information given:
The athlete took 5 minutes and 30 seconds to complete a 3,000 meter race.
2. Convert the time to a standard form for clearer understanding:
The time taken is 5 minutes and 30 seconds.
3. Express the final answer in a readable format:
The athlete took 5 minutes and 30 seconds to complete the 3,000 meter race.
In summary:
- The students start their lessons at 8:10 AM.
- The athlete took 5 minutes and 30 seconds to complete the 3,000 meter race.
