Vectors -- Driving a car between time zones... 1. The problem statement, all variables and given/known data A man is driving a car is 5000m due west from the line marking the eastern time zone. He travels at 30m/s along a straight road that runs 30 degrees north of east. How much time does it take the man to get to the eastern time zone 2. Relevant equations 3. The attempt at a solution I drew it out on a cartesian plane and tried the cos 30 degrees= 5000/hypotenue I know you have to find out the hypotenuse then use the 30m/s to get the time but somehow I'm not getting the right answer..
