1 km = 1000 m
72 km 200 m = 71 km 1200 m
72 km 200m - 48 km 600 m = 71 km 1200 m - 48 km 600 m = 23 km 600 m
or
72 km 200 m - 48 km 600 m = 72 200 000 m - 48 600 000 m = 23 600 000 m = 23 600 km
72 km 200 m = 71 km 1200 m
72 km 200m - 48 km 600 m = 71 km 1200 m - 48 km 600 m = 23 km 600 m
or
72 km 200 m - 48 km 600 m = 72 200 000 m - 48 600 000 m = 23 600 000 m = 23 600 km
