The information for a dragline operation is given:
Bucket capacity: 20 \( \text{m}^3 \)
Bucket fill factor: 0.9
Digging and filling time: 20 s
Swinging (to and fro) time: 32 s
Dumping time: 10 s
Dragline utilization: 90%
The output of the dragline, in \( \text{m}^3\,\text{h}^{-1} \), is . (rounded off to one decimal place)
