Calculation of Average Speed

To calculate the average speed of the tourist, we need to find the total distance traveled and the total time taken.

The tourist traveled for 2 hours by car at a speed of 85 km/h, 3 hours by train at a speed of 60 km/h, and 5 hours on foot at a speed of 5 km/h.

Let's calculate the total distance traveled:

- Distance traveled by car: 2 hours * 85 km/h = 170 km - Distance traveled by train: 3 hours * 60 km/h = 180 km - Distance traveled on foot: 5 hours * 5 km/h = 25 km

The total distance traveled is 170 km + 180 km + 25 km = 375 km.

Now, let's calculate the total time taken:

- Time taken by car: 2 hours - Time taken by train: 3 hours - Time taken on foot: 5 hours

The total time taken is 2 hours + 3 hours + 5 hours = 10 hours.

Finally, we can calculate the average speed by dividing the total distance traveled by the total time taken:

Average speed = Total distance / Total time = 375 km / 10 hours = 37.5 km/h.

Therefore, the tourist traveled with an average speed of 37.5 km/h.
