Annie took a trip consisting of three segments at three different speeds: she drove a distance of (5D) at a speed of (2v), then a distance of (4D) at a speed of (3v), then a distance of D at a speed of (6v). In terms of D & v, the average speed of Annie's trip was?
$$A.\ \frac{11v}{3}$$
$$B.\ \frac{10v}{3}$$
$$C.\ 3v$$
$$D.\ \frac{5v}{2}$$
$$E.\ 2v$$
The OA is D.
I'm confused with this PS question. Experts, any suggestion about the solution? Thanks in advance.
