The eastern time zone would the opposite side of the angle made by his car. So this means he would be traveling 30cos30 m/s completely in the east direction. Or approximately 26 m/s in the East direction. 5000 m divided by this answer results in approximately 192 seconds. I would use a calculator to get a more exact answer

Answer:
Average Velocity = - 1.22 cm/s = - 0.0122 m/s
Explanation:
The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:
Average Velocity = Total Distance Covered/Total Time Taken
Average Velocity = (Final Position - Initial Position)/Total Time Taken
Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)
Average Velocity = (- 2.8 cm)/(2.3 s)
<u>Average Velocity = - 1.22 cm/s = - 0.0122 m/s</u>
here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.
