Could someone review my answers and tell me if i am on the right track? 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 could someone review my answers and tell me if i am on the right track? you!
