 So this is our second measurement video and here we're going to be measuring the map scale. Now the map scale is generally located sort of off to the edge sometimes it'll be in one of the other corners, but in this case it's in this upper. Left right hand corner, excuse me, and it shows the scale for both kilometers and miles. Since this is a science class we use metric and so we're going to be using the kilometers and again in order to get a very accurate measurement i'm going to want to zoom in, so now I have to also change my positioning on it, so I can clearly see my map scale. And we're starting at the zero point and we want to measure over to the 30 kilometer mark and that gives me a measurement of 103 pixels down here at the bottom. So if you use that measurement, which is our map scale, as well as the map distance from Newberry and Camden from the last video, you should be able to test out the calculation and come up with a value about the same as what was mentioned in the lab menu. That lets you know you're doing the calculation correctly. You got one more video, which is the measurement that you're going to be calculating and that'll be in the next video.
