I'm thinking it's either BC & DE or CD & DF, but I'm not sure :/

Hey :)

theeric · Answer

If I remember correctly, the area underneath the curve (or lines) is the displacement. So, does that help you yet? I'm not saying you should know the answer yet, but does that help?

anonymous · Answer

Yeah, that gives me a general idea~

theeric · Answer

To make sure exactly, you'll find the area like I will in the picture. I'll use the interval from C to D as an example.|dw:1374977175829:dw|

$7\times 2+\frac{1}{2}7\times 2=14+7=21$
