A motorist drives north for 40.0 min at 90.0 km/h and then stops for 15.0 min. He then continues north, traveling 130 km in 2.00 h.

(a) What is his total displacement?(b) What is his average velocity?
Answered by bobpursley
total displacement= 40/60 * 90 + 120*2 N

avg velocity= total dislacement/total time

Total time is 3 hrs.
