To solve this problem, we need to remember that distance is equal to speed multiplied by time. However, the time given is in minutes, and the speed is in km/h. So, we first need to convert the time from minutes to hours by dividing by 60.

1. For the first part of the journey:
Time = 31.5 minutes = 31.5/60 hours = 0.525 hours
Speed = 80 km/h
Distance = Speed * Time = 80 km/h * 0.525 hours = 42 km

2. For the second part of the journey:
Time = 16 minutes = 16/60 hours = 0.267 hours
Speed = 75 km/h
Distance = Speed * Time = 75 km/h * 0.267 hours = 20 km

3. The total distance of the journey is the sum of the distances covered in the first and second parts.
Total Distance = 42 km + 20 km = 62 km

So, the correct answer is 62 km.
