: This is apparently from an old walk and bike puzzle:
: 2 girls and a guy want to travel 200 miles on a straight path.
: All 3 are together, and have one bike.
: The girls walk at 2mph, bike at 24mph.
: The guy walks at 9mph, bikes at 44mph.
: Only one can use the bike at a given time.
: What is the minimum time in which they can all
: get to the 200 mile point, and how do they do it?
: I've been trying this for a while but can't get anywhere.
: Can someone help, please.
I would just put the two girls in the canoe and bike the 200 miles.
