    Modelling and problem solving - quadratic equations

    Can you help with the following problem?

    Tom leaves town A and rides at a constant speed towards B. Julie leaves town B at the same time that Tom leaves town A, and travels towards town A. Julie rides at a speed that is 5km/h faster than Tom. Town B is 100 km from town A. They meet after 4 hours. How far has Julie travelled at the time that they meet?
