.

The rate of work of each worker is  3%2F%283%2A3%29 = 1%2F3 of a truck per hour.


Therefore, the answer is OBVIOUS: 3 hours are needed for 1 worker to load 1 truck.

There are multiple ways to solve problems like this....

Here is another solution similar to the one shown by the other tutor.

It takes 3 men 3 hours to load 3 trucks. The number of man-hours per truck is then (3*3)/3 = 3.

So if only 1 man is working, and the number of man-hours per truck is 3, it will take 3 hours.

I personally would solve this example by simple logical reasoning: 1/3 as many trucks to load, and 1/3 as many men, means the same amount of time. ANSWER: 3 hours.
