The minimum time needed to complete all the jobs can be calculated by determining the time taken by each job and then finding the maximum time among them.

Step 1: Calculate the time taken by each job
- Job P takes 30 minutes and needs to be performed on 2 objects, so the total time required for job P is 30 minutes * 2 objects = 60 minutes.
- Job Q takes 20 minutes and needs to be performed on 3 objects, so the total time required for job Q is 20 minutes * 3 objects = 60 minutes.
- Job R takes 60 minutes and needs to be performed on 1 object, so the total time required for job R is 60 minutes * 1 object = 60 minutes.
- Job S takes 15 minutes and needs to be performed on 4 objects, so the total time required for job S is 15 minutes * 4 objects = 60 minutes.

Step 2: Find the maximum time among the jobs
The maximum time required among all the jobs is 60 minutes.

Step 3: Convert the maximum time into hours
Since there are 60 minutes in 1 hour, the maximum time of 60 minutes is equal to 1 hour.

Therefore, the minimum time needed to complete all the jobs is 1 hour.
