First four tasks = 8 seconds
Next four tasks = 8 seconds
Last two tasks = 8 seconds
The total number of seconds to perform all tasks is 24 seconds.
The throughput, which would be the number of tasks per second, is calculated by taking the number of tasks and dividing by the number of seconds:
10 tasks / 24 seconds = 5/12 or 0.4167 tasks per second
