5.1 km is the greater distance.5001 m = 5.001 km < 5.1 km
Convert to same units, then can compare: 1 km = 1000 m → 600 km = 600 x 1000 m = 600,000 m > 5 m → 600 km is greater then 5 m.
9000 meters is greater because it equals 9 km
4 km = 4000 metres. You decide which is greater.
There are 1,000 metres (m) in a kilometre (km) so 600 km = 600,000 m. 600,000 m is much greater than 5 m so 600 km is greater.
