Answer :
Final answer:
The average velocity of the car during the entire trip is 41.84 mi/h.
Explanation:
To determine the average velocity of the car during the entire trip, we need to calculate the total displacement and divide it by the total time.
The total displacement is the sum of the individual displacements: 13.7 mi + 28.6 mi + 43.2 mi = 85.5 mi.
The total time is the sum of the individual times: 13.7 mi / 53 mi/h + 28.6 mi / 47 mi/h + 43.2 mi / 36.6 mi/h = 0.258+0.609+1.18 = 2.047 hours.
Therefore, the average velocity of the car during the entire trip is 85.5 mi / 2.047 h = 41.84 mi/h.
