    Rational Equations

    (Note that most of your answers are algebraic expressions involving .)
    A car starts on a trip and travels at a speed of 55 mph. Two hours later, a second car starts on the same trip and travels at a speed of 65 mph.
    When the second car has been on the road for hours, the first car has traveled miles_________ and the second car has traveled miles________.
    At time the distance between the first car and the second car is_________ miles.
    The ratio of the distance the second car has traveled and the distance the first car has traveled is__________ .
    The second car catches up with the first car___________ hours after the departure of the first car. (Those are some determined drivers!)
    Hint: If you are having trouble with the last part of this problem reread the question carefully. It's not my wording, and if it's any consolation, I got hung up on it myself at first.


    Please help I do not understand this problem and how to solve it

    Re: Rational Equations

    1 = 110 + 55t
    2 = 65t
    3 = 110 - 10t
    4 = (22 + 11t)/13t
    5 let 110 - 10t = 0, therefore answer is 11 hours
