    Explanation:
    Time taken to walk a distance and riding
    back to same place where she started=7
    hr20 min=440 min.
    Time taken to walk both ways=10 hr 40
    min=640 min
    So time taken to walk that distance one
    way=640/2=320 min
    Time taken to ride that distance one
    way=440-320=120 min
    Therefore time taken to ride back both
    ways=2x120=240 min=4 hr
