The table shows measurements for a person.
Table
| Condition | Heart rate in beats per minute | Stroke volume in cm3\mathrm{cm^3}cm3 per beat |
|---|---|---|
| Resting | 60 | 70 |
| Exercising | 120 | 90 |
Use the equation:
cardiac output=stroke volume×heart rate \text{cardiac output}=\text{stroke volume}\times\text{heart rate} cardiac output=stroke volume×heart rateBy how much does cardiac output increase, in cm3 min−1\mathrm{cm^3\,min^{-1}}cm3min−1?
