This is a uniform rates, work or job problem.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Jake's rate plus Jennie's rate is equal to the sum of their rates working together.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The job is \"unload the truck\". Jake goes at 1/40 jobs per minute and Jennie goes at 1/60 jobs per minute. If Jake and Jennie both work at this task at the same time, their combined rate is \"1%2F40%2B1%2F60\" jobs per minute. Basic arithmetic will render the value. If you want how many minutes per job, then find the reciprocal.
