A restaurant's dining room has 30 tables and the waiter takes 10 minutes to set 8 tables.
00:09
And we are asked at this rate, how long will it take the waiter to set all the tables? so we are actually given the rate at which the waiter sets the tables in the question.
00:28
It's eight tables for every 10 minutes.
00:36
And that's indicated here that it's a rate, so that's the clue.
00:41
So if we know the rate, we can calculate the number of tables that would be set equal to the rate at which they are set times how long is spent setting them.
01:01
So if we set, if we could set one table every five minutes, and we set tables for five minutes, that means we've set one table.
01:10
If we set one table every five minutes and we set tables for ten minutes, that means we've set two tables.
01:18
So the dining room has a total of 30 tables, so the total number of tables set is going to be 30...
