Blowing Bubbles

John is blowing bubbles from point $P$ which is $1$ m above the ground. Then a bubble travels along the path $P \to Q \to R,$ where it lands and bursts. The distance of the path $P\to Q$ and that of $Q\to R$ are the same, which is $1.5$ m. The time taken flying each of those two paths is also the same, which is $2$ seconds. What are the magnitude of the average speed and the magnitude of the average velocity, respectively, of the bubble traveling from $P$ to $R?$
