Answer:
The average speed of car is 67 kilometers per hour.
Step-by-step explanation:
Given that:
Distance travelled in one hour = 45 km

Total distance = 45+156 = 201
Total time = 1+2 = 3 hours
Average speed of the car =
Average speed of the car =
Average speed of the car = 67 km/hr
Hence,
The average speed of car is 67 kilometers per hour.
