The Marabyn problem requires students to recommend a distance for someone to travel on a bus and a walking time to complete the journey home. The complicating factor is that there is a given window of time for Marabyn to complete her journey. In the second part of the problem students are required to generalize their answer using the distance formula. Please email us.
