<PRE><B>Question 1128765</B>
7 = k/10
:
k = 70
:
k is the constant of proportionality
:
x = 70/n, where n is the number of workers and x is amount of time for the n workers to complete the job
: 
x = 70/14 = 5
:
it takes 5 hours for 14 bricklayers to complete the job
:
alternate approach
:
the job takes 7 * 10 = 70 man hours to complete
:
we have 14 workers, therefore
:
70/14 = 5 hours for the 14 workers to complete the job
