Now you plan to make a letter B by yourself. The stages to make a B should be $($in this order$)$ A: Bend a small straight piece to U form, B: Bend another small straight piece to U form, C: Make a strong straight base piece, D: Attach the two smaller U pieces to the base piece to creat a B$.$ Assume the following amount of work in seconds is required at each station: A: $30$ secs$,$ B: $29$ secs$,$ C: $45$ secs$,$ and D: $59$ secs$.$ Furthermore, assume three class mates come over, and each of you is assigned to exactly one task $($A$-$D$).($Assume you want to make many Bs$,$ i$.$e$.,$ perform the calculations for a continuous process.$)$ What is the cycle time of your process $($secs$)?$
