You drive a beat-up pickup truck along a straight road for 8.4 km at 70 km/h, at which point the truck runs out of gasoline and stops. Over the next 30 min, you walk another 2.0 km farther along the road to a gasoline station.
(c) What is your average velocity `v_(avg)` from the beginning of your drive to your arrival at the station ? Find it both numerically and graphically.

Explanation

To find the average velocity \( v_{avg} \) from the beginning of your drive to your arrival at the gasoline station, we can follow these steps:

### Step 1: Calculate the total displacement
The total displacement is the sum of the distances traveled in each segment of the journey.

1. Distance from A to B (driving distance): \( X_{AB} = 8.4 \, \text{km} \)
2. Distance from B to C (walking distance): \( X_{BC} = 2.0 \, \text{km} \)
