Q10

$The total distance traveled $=$ the area under the graph. We can split the graph into a rectangle and a square.$

$$Area of rectangle $10ms^{-1} \times 30s = 300m$

$$Area of triangle $\frac{1}{2}10ms^{-1} \times 10s = 50m$

$\therefore $ total distance traveled $ = 350m$

Q11

$v=\frac{d}{t}, d=350, t=40s$

$\therefore v = \frac{35}{4}ms^{-1}$
