An assembly process consists of three tasks: Task#$1,$ Task#$2,$ and Task#$3.$ It takes $2$ minutes to complete Task#$1,5$ minutes to complete Task#$2,$ and $3$ minutes to complete Task#$3.$ The product is assembled in an assembly line with three workers and each worker performs only one task. Estimate the Throughput Rate $($per hour$)$ for this assembly process in a steady state operation. Please help! Thank you!
