Why it can husk at least 12 dozen years of cord per hour? What a man and at most 18 dozen years of cord per hour. All right, based on this information, what is a possible amount of time in hours that it could take Wyatt to husk 72 dozen years of court? Cool. Good for ya. So they gave us two ranges, right?

So they gave us the bottom range. That why it can husk 12 dozen years of corn per hour. So I'm going to write that. And at most he can do 18 dozen years of corn per hour. So this is his range. And they're saying, Well, if he has 72 years of corn, how many hours would it take him to do it?

What is a possible amount of time so it could be any amount of time but you can just put one that makes sense. So if you want to do this, well, let's just find the range of hours, the minimum amount of hours that would take him and the maximum have hours that would take him and just pick a number in between. So how do we do that? Well, let's start with the with the lower end with his weakest days. So when he's doing 12,000 an hour, and he has 72 to do, how many hours would would that take him? Ooh, good question.

So what do you want to do is take 72 total number of dozens of ears, divide that by 12 dozen, and you'll get six. So it'll take him six hours to complete 72 dozen ears of corn if he's going at the rate of 12 dozen dozens of points per hour. You're with me. I know you are good. Thank you for saying Yes. All right.

So now for the higher end went on he when he's on his good day, got his coffee. He got a big meal in his belly. And he started a fresh with on eight hours of sleep. What is he doing so he's doing 18,000 an hour so again, we just 72 divided by 18 That'll give us four hours. Okay? So that means he could either finish this whole thing in four hours when he's going really fast or in six hours.

So just give that at a number in between and they'll be happy with them. They'll give you full points. So, five hours works. Anything really between four and six.
