You can put this solution on YOUR website!
Let:\r
\n" ); document.write( "\n" ); document.write( "1/25 - is the part A makes in a minute
\n" ); document.write( "1/18 - is the part B makes in a minute\r
\n" ); document.write( "\n" ); document.write( "\"1%2F25%2B1%2F18=43%2F450\"\r
\n" ); document.write( "\n" ); document.write( "43/450 is the part they can do together in a minute.\r
\n" ); document.write( "\n" ); document.write( "Now I'll let \"t\" stand for how long they take to do the job together. Then they can do 1/t per hour, so 43/450 = 1/t. Flip the equation, and you get that t = 450/3 or 150.\r
\n" ); document.write( "\n" ); document.write( "\"1%2F25%2B1%2F18=1%2Ft\"
\n" ); document.write( "\"43%2F450=1%2Ft\"
\n" ); document.write( "\"t=150\"\r
\n" ); document.write( "\n" ); document.write( "They can complete the job together in 150 minutes! :)
\n" ); document.write( "
\n" );
