If Chad can paint a room in 2 hours, he can paint 1/2 room per hour. Cassie can then paint 1/3 room per hour.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Together, they can paint $\"1%2F2%2B1%2F3=3%2F6%2B2%2F6=5%2F6\"$ room per hour. So together they can paint one room in $\"6%2F5\"$ hour. $\"6%2F5\"$ is 1 and 1/5. 1/5 hour is $\"60%2F5=12\"$ minutes. So working together, they can paint the room in 1 hour and 12 minutes. \n" ); document.write( "
