do an excel file to solve the example

A$)$ Calculate the number of trucks

theoretically required and the production of

this combination

B$)$ Calculate the expected production if two

trucks are removed from the fleet

Shovel production at $100\%=283BC\frac{M}{h}$

Job efficiency $=0\mathrm{.}75$

Truck capacity $=15\mathrm{.}3BCM$

Truck cycle time $($excluding loading$)=0\mathrm{.}5h$
