A 20-t capacity, articulated rear-dump truck hauls ore to the surface. Ore is placed in the truck by a 6.1-m3-capacity remotely
operated loader near the entrance of the stope. The truck hauls the ore 550 m along a nearly level drift, and then it hauls the ore
1,450 m up a 10% gradient to the surface. After reaching the surface, the truck travels another 200 m to the mill, where the ore is
dumped into a crusher feed bin. Find the total travel time of the truck considering the approximate hauling speeds over different
gradients below
- Up a 10% gradient, loaded ≈ 6.4 km/h
- Over a level gradient, loaded ≈ 16.1 km/h
- Over a level gradient, empty ≈ 20.3 km/h
- Down a 10% gradient, empty ≈ 15.8 km/h
