In Reincarnated as a Slime, what are the approximate distances between locations, aka the scale of the map? Below is a map of the world in which Reincarnated as a Slime happens but there isn't any indication of the scale of the map. Are there any indications of distances between locations with which estimates could be derived? For example, could one estimate distances based on the time it took Rimuru to get to Dwargon?
This might not be approximate but I'll mention it anyways. Before rimuru tempest showed up it might have taken them the time stamp of:

Dwargon - 2 Months
Beast Nation - 5 Months
Demon Lord Milim's Place - Fastest pace - 8-9 Months Slowest Pace - 11 Months
Holy Reuben Empire - Fastest pace - 10 Months Slowest Pace - 12-13 Months
Kingdom of Ingrasia - Fastest pace - 7 Months Slowest Pace - 9 Months
Barren Lands - Fastest pace - 13 Months Slowest Pace - 15 Months

Again this is not approximate but hope it eases the minds.
