Find (a) Distance travelled to plant. (b) Displacement. (c) Average speed. (d) Average velocity. Time to reach plant is 300s. Now do the extra sheet on the snail race Worked example Brian North

Using Scale Diagrams A boy ran 200m due north followed by 200m to the east. What distance does he travel? What was his resultant displacement? If it took 3mins 20 s to run this what was his speed and velocity? Can you find the displacement without using a scale diagram?. Worked example Tutorial questions page 5 and 6 Qu 4 to 9
