Final answer:
The provided information does not include distances and speeds for each segment of the trip to calculate the total driving time.
Step-by-step explanation:
To calculate the total amount of time spent driving from one city to another, it is essential to know the distance between the cities and the speeds at which the person travels for each part of the trip. Without specific distances and speeds for each segment of the trip, it is not possible to determine the total driving time. The problem shared does not contain enough information to solve for the total time spent driving, as it only provides examples on how to calculate average speed but does not provide any actual data related to the question. For instance, if a car travels 150 kilometers in 3.2 hours, the average speed would be calculated by dividing the distance by the time, thus the average speed would be 150 km divided by 3.2 h, which equals approximately 46.88 km/h (rounded to 47 km/h for simplicity).
