Analysis of Conveyor Systems

$5\mathrm{.}13$ A roller conveyor is $250ft$ long and its velocity is $80f\frac{t}{m}in.$ It is used to move pallets between load and unload stations. Each pallet carries $10$ parts. Cycle time to load a pallet is $0\mathrm{.}25$min and one worker at the load station is able to load pallets at the rate of $\frac{4}{m}in.$ It takes $0\mathrm{.}20$min to unload at the unload station. Determine $($a$)$ the center$-$to$-$center distance between pallets, $($b$)$ the number of pallets on the conveyor at one time, and $($c$)$ the hourly flow rate of parts.
