Weather Observation Station 18

Question Link

Consider P1(a,b) and P2(c,d) to be two points on a 2D plane.

• a happens to equal the minimum value in Northern Latitude (LAT_N in STATION).

• b happens to equal the minimum value in Western Longitude (LONG_W in STATION).

• c happens to equal the maximum value in Northern Latitude (LAT_N in STATION).

• d happens to equal the maximum value in Western Longitude (LONG_W in STATION).

Query the Manhattan Distance between points P1 and P2 and round it to a scale of 4 decimal places.

The STATION table is described as follows:

where LAT_N is the northern latitude and LONG_W is the western longitude.

SELECT ROUND(ABS(MAX(lat_n)-MIN(lat_n)) + ABS(MAX(long_w)-MIN(long_w)),4)
