WHAT is better walking 5 kilometers or 4987 meters?

Answer 1

Given that 4987 metres is a more precise unit of measurement than 5 kilometres, you could argue that it would take more skill to walk exactly 4987 metres than it would to cover an approximate measurement of 5 kilometres.

Answer 2

Walking 5 kilometers is better as it is a longer distance than 4987 meters. A kilometer is equal to 1000 meters, so 5 kilometers equals 5000 meters.
