1. The problem statement, all variables and given/known data Jeremy is training for a boxing match. He runs due north at an average speed of 16km/h for the first 8.0 km and returns to the training camp at an average speed of 10 km/h. Calculate his average speed and his velocity. 2. Relevant equations Vavg = Total Distance / Total Time Average Velocity = Final displacement / Total time taken 3. The attempt at a solution 16 km/h for first 8.0 km = 0.5 hours 10 km/h for the trip back = 0.8 hours Total time taken = 1.3 hours Total distance = 16 km Average speed = 16/1.3 =12.3 km/h. The answer on my sheet is 12km/h. Am I doing something wrong or is it just rounded? For average velocity, would it be 0? Since there is no displacement from the starting point? I am just starting physics, and I just need guidance in the right direction. Thank you.
