Please show work and answer all questions :D

A company provides prototyping services using 3D printing. They are preparing to start a new project that involves prototyping two products with the following operations/times: - Setting up materials and tooling for product one (activity identifier: s1), (time required 1/2 of an hour). - Setting up materials and tooling for product two (activity identifier: s2), (time required: 1/2 of an hour). There is only one operator of the only machine available for these two products so the s1 cannot happen at the same time as s2. - 3D Printing product one (activity identifier: p1 ), (time required: 1.5 hours). - 3D Printing product two (activity identifier: p2), (time required: 1.5 hours). Remember, there is only one machine available to do the 3D printing. Once the 3D printing operation is completed, the part should rest for some time so the composite properly sets. - Resting product one (activity identifier: r1 ), (time required: 3/4 of an hour). - Resting product two (activity identifier: r2 ), (time required: 3/4 of an hour). After the product rested for the required time, some detailing and final touches are required. - Detailing product one (activity identifier: d1), (time required: 1/4 of an hour). - Detailing product two (activity identifier: d2), (time required: 1/4 of an hour). As the machine is a fully automated machine it is possible to leave the 3D printing of the first product happening, while setting up the materials and tooling for the second product. Also, it is possible to do the resting of the first product while doing the 3D printing of the second product. Based on all this information, how many minutes have elapsed since starting the process until they have BOTH products fully finished and detailed? minutes What would be the critical path of the project?
