Homework Help: Homework problem: Average speed and time

  1. Apr 2, 2009 #1
    1. The problem statement, all variables and given/known data

    A golfer rides in a golf cart at a speed of 3.10 m/s for 24.0 s. She then gets out of the cart and starts walking at an average speed of 1.30 m/s. For how long (in seconds) must she walk if her average speed for the entire trip, riding and walking, is 1.90 m/s?

    2. Relevant equations

    3. The attempt at a solution
    I don't know where to begin with this problem. I assume that distance plays a factor in the problem, but I'm not sure.

    Find the distance traveled in the golf car. Assume she walks for t s. Find distance she walks in terms of t. Find the total distance and total time. You know the average velocity. From that find t.
