Uniform rate for doing a task:
RT=J to relate rate, time, amount of task or job.

Agents doing work together form an additive rate. 4 workers, rate is 4R. n workers, rate is nR.

Let r be one-worker rate, and t be the unknown time for 2 workers together.

Solve the system, with the main goal to find value for t.
