Final answer:
The athlete's systolic pressure of 100.0 mmHg is equivalent to 13.30 kPa when converted and rounded to two decimal places.
Step-by-step explanation:
The systolic pressure of an athlete after an hour-long swim is 100.0 mmHg. To convert this pressure into kilopascals (kPa), we use the conversion factor that 1 mmHg = 133 Pa. Since there are 1,000 pascals in a kilopascal, we then divide by 1,000 to complete the conversion.
So, the calculation is as follows:
100.0 mmHg * 133 Pa/mmHg = 13,300 Pa
13,300 Pa / 1,000 = 13.30 kPa
Therefore, the athlete's systolic pressure of 100.0 mmHg is equivalent to 13.30 kPa when rounded to two decimal places.
