Normally I would ask my teacher, but since we had the day off and it's due the day we get back, I can't question him. 1. The problem statement, all variables and given/known data What is the difference between calculating the average speed and John's speed (questions g and f)? and how do you find displacement for a distance-time graph (question f), do you just add all the sections where John is moving or do you do the whole journey? 2. Relevant equations Speed = distance divided by time. Displacement = velocity multiplied by time. 3. The attempt at a solution I have only attempted f, because I just want to the know the difference between question g and f. 25+7=32-32=0. Thanks in advance.
