there are multiple questions and they corespond with one another

Caprock Production wants to know how many workstations minimum will be needed to manufacture a product consisting of 10 steps and a total production time of 80 minutes. The throughput required to meet demand is 60 units per day. Assume a work day of 8 hours. O a. 10 workstations O b.8 workstations O c. 6 workstations O d. 4 workstations For Caprock Production in the problem above, calculate the efficiency of the line if it uses the minimum number of workstations required as just calculated above taken in relation to the total production time required of 80 minutes. O a. more than 95% but less than or equal to 100% Ob.more than 90% but less than or equal to 95% O c. more than 85% but less than or equal to 90% O d. more than 80% but less than or equal to 85% For the Caprock Production problem above assume the following steps are involved. Task (Work Element) Predecessor Time (Duration) 8 | oo | Co B 8 8 F G -Tolmio col coll col collo H 1 8 What tasks will go into the third workstation, assuming the predecessor sequence above, starting with the first task and not giving consideration to the task durations? O a. C only b.B,C,D O.C. E, F, G d. E only
