An investigation was carried out to measure the respiratory frequency and tidal volume of a Thoroughbred racehorse at rest and while galloping on a high-speed treadmill.
The results are shown in the table below.
| Physiological State | Mean breathing rate / breaths min−1\text{breaths min}^{-1}breaths min−1 | Mean volume of air in one breath / dm3\text{dm}^3dm3 | Mean volume of air breathed per minute / dm3\text{dm}^3dm3 |
|---|---|---|---|
| Rest | 12.5 | 6.2 | 77.5 |
| Galloping at 12 m s-1 | 116.4 | 13.7 | ? |
Calculate the mean volume of air breathed per minute when galloping at 12 m s-1.
Give your answer to one decimal place.
