Oh, my horsey friends, please double-check my book learning.
I’m figuring that Character A will take about 2 and a half hours to cover four miles on a deer path through a heavily wooded area. She’s got about fifty very short characters with her, so isn’t walking at top speed.
Returning, she’s mounted on a horse. Is it reasonable to think that she could cover the same distance in about forty-five minutes? If she were in a hurry, (and she is) how fast could she safely go? This is a path with which she is familiar, but a new horse.
