<PRE><B>Question 102895</B>
It takes 7.5 hrs for 16 people to place flyers on each of the kiosks on campus.  

How long would it take 13 people?

Time taken by 16 people to place flyers on each of the Kiosks on campus = 7.5 hours

Time taken by 1 person to place flyers on each of the Kiosks on campus = 7.5/16 hours

                                                                   = 46875hours
                                                                   = 0.47 hours

Time taken by 13 people to place flyers on each of the Kiosks on campus= 0.47*13

                                                                   = 6.11 hours

 Hence the solution
