Question

Larry leaves home at 2:08 and runs at a constant speed to the lamppost. He reaches the lamppost at 2:15, immediately turns, and runs to the tree. Larry arrives at the tree at 2:29. What is Larry's average velocity during his trip from home to the lamppost, if the lamppost is 308.0 m west of home, and the tree is 688.0 m east of home?

Answer 1

velocity is change of position (a vector) per time.

change of position: final position-initial
= 688E+308W=380W

avgvelocity=380W/total time.
