A student drove to the university from their home and noted that the odometer reading of their car increased by 14.0 km. The straight-line distance (that is, the magnitude of displacement) between the student's home and the university is 10.0 km. This trip took 30.0 min. The student then returned home by the same path 7.00 hours after they left home. Whch of the following statement is correct? The average speed of the student during this whole day is 20.0 km/hour. The average speed of the student during this whole day is 28.0 km/hour. The average speed of the student during this whole day is 2.00 km/hour. The average speed of the student during this whole day is 0 km/hour.
