# Just a few questions.

*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.*
