Asked by Lyna

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?
Answered by Annamarie
(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

Same problem different numbers
