Hi

 Marie rode (6mph) her bicycle from her home to the bicycle shope in town and  

then walked(3mph) back home. 

total travel time was 1 hour

Let x and (1hr-x)represent the time riding and walking

Question states***  NOte: D =r*t  (distance same riding or walking)

 6mph*x = 3mph(1hr-x)

    9x = 3

     x = 3/9 = 1/3 hr, the time riding.  Time walking was 2/3 hr

and D+=+6mph%2A1%2F3hr+=+2mi to the bicycle shop

 3*2/3 = 6*1/3 = 2mi
