1. Assume the coordinate system designates east as the positive direction.  
2. Since the car is traveling east, its displacement after any time interval (including 60 seconds) will be to the east, meaning its position is in the positive direction.  
3. When two positive numbers are multiplied, the result is positive.  
4. Therefore, 60 seconds after the car passes the camera, its position will be positive, and multiplying two positive numbers also gives a positive result.
After 60 seconds, the car's position is positive because it's moving east. Multiplying two positive numbers results in a positive number.
