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.
