    chuanhui asked me for the ans. to question 48, so:
    r 12 steps + w28 steps = 102 sec

    r 20 steps + w20 steps = 102 - 12 = 90 sec

    r 12 steps + w28 steps = 102 sec

    r 8 steps - w 8 steps = 12 sec

    r 4 steps - w 4 steps = 6 sec

    r 12 steps + r 28 steps = 102 - 6(28/4)
    = 102- (6 x 7)
    = 102 - 42
    = 60 sec
