Question

A man driving a car is exactly 5000 meters due west from the line marking the eastern time zone. He

travels at 30.0 m/s along a straight road that runs in a direction 30.0° north of east. How much time does
it take the man to get to the eastern time zone?

Answer 1

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
