Answer:
8,333 total population
Step-by-step explanation:
Question can be restated as "5000 is 60% of what number?"
5000 = .6x
x = 5000/0.6
x = 8,333.33
There is a formula for that;
Total time = (Worker 1 * Worker 2) / (Worker 1 + Worker 2)
Total time = (80 * 120) / (80 + 120)
Total time = 9,600 / 200
Total time = 48 minutes
