Question 1144883
<br>
There are multiple ways to solve problems like this....<br>
Here is another solution similar to the one shown by the other tutor.<br>
It takes 3 men 3 hours to load 3 trucks.  The number of man-hours per truck is then (3*3)/3 = 3.<br>
So if only 1 man is working, and the number of man-hours per truck is 3, it will take 3 hours.<br>
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.
