To solve the given Tournament Records problems, we need to understand the most efficient methods to perform each calculation.
### 1. Calculating the time for the Fencing record in minutes:
We are given that the fencing record is 4 hours. We need to convert this time into minutes.
Since there are 60 minutes in one hour, we apply the following calculation:
[tex]\[ 4 \text{ hours} \times 60 \text{ minutes/hour} \][/tex]
- This is a straightforward multiplication problem involving small numbers (4 and 60).
- Since it’s a simple calculation, it can be easily done using mental math.
Result:
[tex]\[ 4 \times 60 = 240 \][/tex]
So, it took 240 minutes to reach the record for fencing.
### 2. Calculating the Shot Put record in centimeters:
We are given that the shot put record is 27 meters. We need to convert this distance into centimeters.
Since there are 100 centimeters in one meter, we apply the following calculation:
[tex]\[ 27 \text{ meters} \times 100 \text{ centimeters/meter} \][/tex]
- This is a straightforward multiplication problem, but involves larger numbers (27 and 100).
- Even though it's not overly complex, some may prefer pencil and paper to ensure accuracy, especially for larger multiplications.
Result:
[tex]\[ 27 \times 100 = 2700 \][/tex]
So, the shot put record is 2700 centimeters.
### Conclusion:
- For the fencing record conversion from hours to minutes, the most efficient method is mental math because the multiplication is simple.
- For the shot put record conversion from meters to centimeters, using pencil and paper to perform the multiplication ensures accuracy, given the slightly larger numbers.
Thus, the final results are:
- Fencing record: 240 minutes
- Shot put record: 2700 centimeters
