Question 292349
If it takes 3 people 4 hours to clean a warehouse, how long will it take 4 people to clean the warehouse?
<pre><font size = 4 color = "indigo"><b>
Since it takes 3 people 4 hours to clean a warehouse, it would take
1 person 3 times as long as that to clean a warehouse, or 12 hours,
and it would therefore take 4 people {{{1/4}}} as long as it would 
take 1 person or 3 hours.
