Final answer:
The vehicle's location is 195 kilometers in the negative direction (opposite to the positive reference direction) from the starting point after 3 hours of driving, as calculated by the formula displacement equals velocity times time, with a velocity of -65 km/h and a time span of 3 hours.
Step-by-step explanation:
To determine the location of the starting point relative to the current location, we can use the concept of displacement. Displacement is the change in position of an object and it's a vector quantity, which means it has both magnitude and direction. Given that the velocity is -65 km/h and the driver has been driving for 3 hours, we calculate the displacement.
Displacement (d) can be calculated using the formula:
d = velocity × time
In this case, the velocity is -65 km/h (indicating direction opposite to the positive reference direction, let's say westward), and the time is 3 hours. So the calculation would look like this:
d = (-65 km/h) × (3 h) = -195 km
This means that the vehicle is now 195 kilometers away in the direct opposite direction of the initial positive direction from the starting point. Since the velocity is negative, we can assume this means the vehicle has moved in the negative direction from the starting point. If the starting point is considered the origin or zero point, this value represents the vehicle's position relative to the starting point after 3 hours of driving.
