Answer:
9] V = [tex]\frac{D}{T} [/tex]
Take any distance value from the graph and its relevant time.
V = [tex]\frac{8}{4} [/tex]
V = 2 m/s
[You will notice that any distance values with its time will give you 2 m/s as its speed. This means that speed is constant throughout.]
10] Take the distance value and its time for the highest peak of B.
V = [tex]\frac{20}{2} [/tex]
V = 10 m/s
