Question: A football halfback dashes 18 m straight down the playing field in 2.8 s (in the positive direction). He is then hit and pressed 2.5 m straight backwards in 1.65 s. He breaks the tackle and runs straight forward another 16 m in 4.4 s.

Part I: Calculate the halfback's average velocity in the horizontal direction for the entire motion, in meters per second.

I want help to find the halfback's average velocity in the horizontal direction for the entire motion.
