The time t required to do a job varies inversely as the number of people working. It takes 2 hr for 5 cooks to prepare the food for a wedding rehearsal dinner. How long will it take 6 cooks to prepare the​ dinner?

If it takes 7 hours for 6 cooks to prepare the food, that means, each cook spends 7 hours basically.
