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?

What is the average velocity for Larry's entire run?

• physics -

it is only his final position and initial position that determines change in position. He ends up 688E of his home

avgveloicty=688E/timetotal
