    select round(abs(max(lat_n)-min(lat_n))+abs(max(long_w)-min(long_w)),4) from station manhanttan distance = |x_1 - x_2| + |y_1 - y_2| we known if i have one vector a have coordinate (x,y) examples (1,1) , (3,4) if we want to calculate distance vector (1,1) to (3,4) , we could manhanttan distanstance
