Posted by Miaow on Friday, August 31, 2012 at 7:31pm.

Could someone please review my answers and tell me if I am on the right track? Thank you!

A student drove to the university from her home and noted that the odometer reading of her car increased by 12.0 km. The trip took 18.0 min. (a) What was her average speed? (b) If the straight-line distance from her home to the university is 10.3 km in a direction 25.0o south of
east, what was her average velocity? (c) If she returned home by the same path 7 h 30 min after she left, what were her average speed and velocity for the entire trip?

a.) average speed: 12 km/18 min=0.67 km/min

b.) average velocity: (must find time first)

t: 10.3 km/ 0.67 km = 15.4 min

average velocity: 10.3 km/15.4 min = 0.67 km/min

c.) average speed: 24 km/450 min = 0.05 km/min

average velocity: 0 km/450 min = 0
