Nathan and Connor had a contest. They wanted to see who could keep from laughing for the longest time. Nathan did not laugh for 4 minutes and 18 seconds. Connor did not laugh for 3 minutes and 47 seconds. How much longer did Nathan keep from laughing?

  4m  18s   =   4*60  + 18   =  258s

- 3m 47s  =     3*60  + 47   =  227s

                                             ____

                                                31 s   longer
