Add 8 minutes 32 seconds + 37 minutes 18 seconds + 15 seconds
The correct answer and explanation is:
Correct Answer: 46 minutes and 5 seconds
Step-by-step Explanation:
We are adding three time values:
- 8 minutes 32 seconds
- 37 minutes 18 seconds
- 15 seconds
Step 1: Add the seconds
- 32 seconds
- 18 seconds
- 15 seconds
Add them together: 32+18+15=65 seconds32 + 18 + 15 = 65 \text{ seconds}
Since 60 seconds = 1 minute, we convert 65 seconds: 65÷60=1 minute and 5 seconds65 \div 60 = 1 \text{ minute and } 5 \text{ seconds}
So, we carry over 1 minute and keep 5 seconds.
Step 2: Add the minutes
Now add the minutes:
- 8 minutes
- 37 minutes
- +1 minute (from the seconds we just converted)
8+37+1=46 minutes8 + 37 + 1 = 46 \text{ minutes}
Step 3: Combine the final result
- Minutes: 46
- Seconds: 5
46 minutes and 5 seconds\boxed{46 \text{ minutes and } 5 \text{ seconds}}
Why this Matters (300-word Explanation):
Understanding how to add time accurately is an important real-life skill, especially in fields such as transportation, broadcasting, cooking, sports timing, and project management. Time is a compound unit that doesn’t follow the decimal system. Instead of 100 seconds making a minute, we have 60 seconds in a minute, and 60 minutes in an hour. This makes calculations involving time a bit trickier.
When adding time, it’s best to add seconds separately from minutes. Once the total seconds exceed 60, we convert that to minutes and seconds. This ensures that the final answer is in proper time format. In our example, we first added all the seconds (32 + 18 + 15 = 65), then converted 65 seconds into 1 minute and 5 seconds. That 1 minute was added to the total minutes (8 + 37 = 45), resulting in 46 minutes. The 5 seconds remained as they are.
Getting a correct answer in such calculations avoids confusion, especially in time-sensitive settings. For example, when calculating total playtime in sports or total time spent on a task, every second counts. Learning this reinforces how units work together and helps build a stronger foundation for more complex time calculations, like subtracting times, converting between hours and minutes, or figuring out average speeds.
Thus, the final answer to 8 minutes 32 seconds + 37 minutes 18 seconds + 15 seconds is: 46 minutes and 5 seconds\boxed{46 \text{ minutes and } 5 \text{ seconds}}
