Walter wants to serve hushpuppies to his guests for his annual fish fry event.  He thinks each guest will eat 5 hushpuppies and he is having 20 guests.  He can cook 10 hushpuppies in 8 minutes.  How long will it take to cook all of the hushpuppies?
He wants to serve 5 hushpuppies to each guest and he is having 20 guests so that's 5*20 = <<5*20=100>>100 hush puppies
He can only cook 10 hushpuppies at a time and he needs to cook 100 hushpuppies so that's 100/10 = <<100/10=10>>10 batches of hushpuppies
Each batch takes 8 minutes to cook and he has 10 batches to cook so it will take him 8*10 = <<8*10=80>>80 minutes
