Billye ran to town at 8 kilometers per hour and then walked back home at 3 kilometers per hour. How far was it to town if the round trip took 11 hours?

  • Algebra -

    Let X be the distance.
    Time = Distance/Speed
    X/8 + X/3 = 11 hours
    Convert to a common denomimator.
    (3X + 8X)/24 = 11
    11 X /24 = 11
    Divide both sides by 11.
    X/24 = 1
    Do you see where to go from here?
