Fast Sally



            Mary and Sally have a catering business.  They have a big wedding reception to cater Saturday afternoon.  Mary is not as fast as Sally is in preparing the hors d'oeuvres.  In fact Sally is 2 ½ times faster than Mary.  Mary arrives early Saturday morning and begins working making the appetizers.  Sally over slept and arrives 2 hours later.  How long will it take for Sally to make as many hors d'oeuvres as Mary?





 Good Luck!!!!!
