please solve for the correct answer for these questions:

Consider a four-step serial process with processing times given in the following list. There is one machine at each step of the process, and this is a machine-paced process. - Step 1: 15 minutes per unit - Step 2: 17 minutes per unit - Step 3: 20 minutes per unit - Step 4: 25 minutes per unit Assuming that the process starts out empty, how long will it take (in hours) to complete a batch of 99 units? (Do not round intermediate calculations. Round your answer to nearest hour.) hours Consider a process consisting of three resources. Assume there exists unlimited demand for the product. - Resource 1 has a processing time of 5 minutes per unit. - Resource 2 has a processing time of 3 minutes per unit. - Resource 3 has a processing time of 6 minutes per unit. The three resources are staffed by different workers individually. The flow diagram is shown above. (Round your Part a answer to 3 decimal places. Enter all other answers as whole numbers.) a. What is the capacity of resource 2 ? units per minute b. What is the bottleneck in the process? Resource c. What is the utilization of resource 2 ? percent d. How long does it take the process to produce 183 units starting with an minutes empty system, assuming this is a worker-paced process
