Find distance between two points --> root( (x2 - x1)^2 + (y2 - y1)^2 ) = root (3^2 + 7^2) = root ( 58), as one unit is two miles then 2* root(58) = 15.23 miles.
I would go with C only because you have the find the median of the lower half of the data set This means that about 25% of the numbers in the data set lie below Q1 and about 75% lie above Q1.
