Arestaurant took 1/10 of an hour to use 1/6 of a package of napkins at this rate how many hours would it take to use the entire package

36 minutes is how long it would take to use a package of napkins

1/10 of an hour is 6 minutes. So if they used 1/6 of a package in 6 minutes, then 6/6 of the package, or the entire package would be used up in 36 minutes (6*6)

The answer is (a) 12-2(-1)(6)2(6)=12

and surely you know how much that is.
