You drive your car along a straight road for 8.4 km at 70 km/h, and then it runs out of petrol and stops. You then walk along the road for 2.0 km in 30 min to reach a petrol station.

(a) What is your overall displacement (in m) from the beginning of your drive to your arrival at the petrol station?

(b) What is the time (in s) from the beginning of your drive to your arrival at the petrol station?

(c) What is your average speed (in m/s) from the beginning of your drive to your arrival at the station?

(d) After getting the petrol, you get driven back to your car on a motorbike. It starts from rest and accelerates at 12 m/s^2. How long does it take to reach your car?
