Q$4\mathrm{.}2($Algo$)$ Assign tasks to workers $|4\mathrm{.}1,4\mathrm{.}41$Consider the following six tasks that must be assigned to four workers on a conveyor $-$ paced assembly line $($i$.$e$.,$ a machine$-$ paced line flow$).$ Each worker must perform at least one task.Time to Complete Task $($seconds$)$Task $130$Task $215$Task $335$Task $440$Task $515$Task $630$The current conveyor $-$ paced assembly line configuration assigns the workers in the following way:Worker $1$: Task $1$Worker $2$: Task $2$Worker $3$: Tasks $3,4$Worker $4$: Tasks $5,6$a$.$ What is the capacity of the current line? $($Enter your answeras a whole number.$)$Units capacity per hour?b$.$ Now assume that tasks are allocated to maximize capacity of the line, subject to the conditions that $(1)$ a worker can perform at most two adjacent operations and $(2)$ all tasks need to be done in their numerical order. What is the capacity of this line now?Note: Round your final answer to two decimal pleces:Capacity of the revised line is $\_\_\_\_\_\_$ units per hour
