A motorist drives north for 30.0 minutes at 62.0 km/h and then stops for 15.0 minutes. He then continues north, traveling 130 km in 1.90 h.
(a) What is his total displacement?
(b) What is his average velocity?

(a) (42min/hr) x (1hr/60min) = 0.7hr
(76.5km/hr) x 0.7 hr = 53.55 km (Part1)
Part2 - 130 km
Part1+part2=53.55km+130km=183.55km
