The answer explains how to calculate the time taken for 10 workers to pack fruit compared to 5 workers.
To determine how long it would take for the 5 people to pack the fruit if the number of workers is doubled, we can use the concept of work done.
When the 5 workers take 4 hours to pack the fruits, the total work done is 5 * 4 = 20 worker-hours.
If the number of workers is doubled to 10, the total work done remains the same, so the time taken would be 20 worker-hours / 10 workers = 2 hours.
