1. The problem statement, all variables and given/known data A pedestrian is jogging on a path and sees a boat coming towards him. He's moving at 10 km/hr and the boat is moving at 20km/hr, how quickly does the jogger approach the boat? 2. Relevant equations I'm guessing these: Vf = vi + a * t D = vi*t +1/2 a * t^2 Vf^2 = Vi^2 +2a * D 3. The attempt at a solution well i converted the speeds to m/s Jogger:2.77 m/s Boat:5.55 m/s other than that I've got no idea I know we need a time and a distance and maybe acceleration?
