C’mon everyone... this land is your land/ this land is my land… no? Ok. Party poopers.

It’s just a vanilla area conversion problem. They give us that 100 kilometers is 62 and

00:38

a half miles so if we take that to the unit level, 1 kilometer is about .625 miles.

00:44

Since 1 kilometer is about .625 miles, this tells us that miles are bigger than kilometers.

00:50

Makes sense. America’s bigger than England.

00:53

They give us the 64 kilometers as part of the question.

00:57

So we can immediately eliminate C and D, since only 2 of the answers are less than 64.

01:02

To convert kilometers and miles to SQUARE kilometers and SQUARE miles, we can just square .625.

01:08

Since we want to find the how many square miles are in 64 square kilometers, we can

01:13

multiply .625 times 64 to get 25 miles squared.

01:19

Looks like the answer is A.

As in… “American Idol is calling…”
