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.
