Question 629658: In order to develop a more appealing cheeseburger, a franchise uses taste tests with 9 different buns, 6 different cheeses, 2 types of lettuce, and 5 types of tomatoes. If the taste tests were done at one restaurant by one tester who takes 10 minutes to eat a cheeseburger, how many hours would it take the tester to eat all possible cheeseburgers?

There are 9*6*2*5 = 540 different cheeseburgers

So...

(540 cheeseburgers)*(10 minutes/1 cheeseburger) = 540*10 = 5400 minutes

Convert to hours to get

(5400 min)*(1 hr/60 min) = 5400/60 = 90 hours

So it will take 90 hours (which is 3.75 days or 3 days, 18 hours) to eat all the possible cheeseburgers.
