There are many early algebra problems with trains. Like ``two trains
1000 miles apart travel towards each other with speed 25 and 35 miles per hour
when do they meet?". The problem which appears in ``Spirit Untamed" unfortunately
is not complete. Trying to match the story of the adventurous girls in ``Spirit Untamed",
one could complete it as follows:

"A train traveling 25 miles per hour leaves the station at 8:00 AM"
and has to stop for an hour every hundred miles to refill water.
Assume the train reaches its destination at 12:00 noon the following day.
How far was the destination away?"
