If 15 men can do a piece of work in 90 days, in how many days can 30 men do the same work?
\n" ); document.write( "-------------
\n" ); document.write( "Number of men and days to do the job are inversely related.
\n" ); document.write( "-------------
\n" ); document.write( "Equation:
\n" ); document.write( "days = k/number of men
\n" ); document.write( "---
\n" ); document.write( "Solve for \"k\":
\n" ); document.write( "90 = k/15
\n" ); document.write( "k = 15*90 = 1350
\n" ); document.write( "-----
\n" ); document.write( "Equation for your problem:
\n" ); document.write( "days = 1350/number of men
\n" ); document.write( "------
\n" ); document.write( "Your Problem: in how many days can 30 men do the same work?
\n" ); document.write( "days = 1350/30
\n" ); document.write( "days = 45
