It takes 25 minutes for 8 people to paint 5 walls.
\n" ); document.write( "How many minutes does it take 5 people to paint 7 walls?
\n" ); document.write( "------
\n" ); document.write( "time is directly related to # of walls and inversely related to # of people
\n" ); document.write( "----
\n" ); document.write( "t = k*w/p
\n" ); document.write( "----
\n" ); document.write( "Solve for \"k\" using \"It takes 25 min for 8 people to paint 5 walls\".
\n" ); document.write( "25 = k*5/8
\n" ); document.write( "k = 40
\n" ); document.write( "------
\n" ); document.write( "Equation for this problem
\n" ); document.write( "t = 40w/p
\n" ); document.write( "----
\n" ); document.write( "Your Problem::
\n" ); document.write( "\"How many minutes does it take 5 people to paint 7 walls?\"
\n" ); document.write( "t = 40*7/5
\n" ); document.write( "t = 8*7
\n" ); document.write( "time = 56 minutes
