7. A petroleum geologist is interested in a long brand new 2 km roadside outcrop. He is working on the limestone formation of this road cut, because this formation is a gas reservoir. Thus, he likes to understand the vertical joint system in terms of their spacing, number and other aspects. His survey along the entire road cut shows that the spacing is very similar all the way. He chooses to count the vertical joints along an only 50 m outcrop segment. He counts 171 joints. Since the joint spacing is very similar along the entire outcrop, he extrapolates the number of joints for the whole outcrop. How many joints does he calculate? Also, what is the density of joints per 15 m of outcrop line?
