Achain of events
three friends, davina, jolene and katie, set out
to the hoppings fairground, travelling on their
three bikes. they lock up the bikes and go to
enjoy their day. when they return, they find two
of the bikes have disappeared. assuming only
one person can ride the remaining bike at a time,
and that it is 12 miles back home, how should
they proceed, to be fair to each other so each
person ends up walking the same distance? the
bike has a speedometer with a mileage counter.
what if only one bike had been stolen?
