  1. The ratio flat vs hill is unknown so you can’t calculate this normally. But since the average for uphill/downhill is also 4 kmph ((1.5h)/6km)), the calculation is: 6 hours * 4kmph = 24km.

  2. x/3 + y/3 +x/4 + y/6 = 6
    x/2 + y/2 = 6
    x+y = 12
    the total distance is 12…..x being the flat part and y
    being the slope..

  3. ans is 24..
    bcos he travels x and y distance to times……
