We can't tell you the height after sitting by the fire
for 10 hours, because you didn't tell us the height
he reached at the end of his walk.
All we can tell you is that whatever his height was
when he came in to get warm, it's
(10 hours) x (3 inches/hour) = 30 inches
shorter after 10 hours by the fire.
