Answer by josmiceli(19441) About Me  (Show Source):
You can put this solution on YOUR website!
( seats made ) / ( time to make them ) = ( seats made ) / ( time to make them )
+2+%2F+11+=+16+%2F+t+
Multiply both sides by +11t+
+2t+=+11%2A16+
+2t+=+176+
+t+=+88+ min
-------------
You can also solve this way:
it will take him half as long to make just 1 seat
or +11%2F2+=+5.5+ min
16 seats will take him 16 times as long, or
+16%2A5.5+=+88+ min
