Answer 1

Calculation of the Distance Covered by the Tourist

To calculate the distance covered by the tourist on the last day, we need to analyze the given information. Let's break it down step by step:

1. The tourist walked for 4 days. 2. Each day, the tourist walked 2 km less than the previous day. 3. The total distance covered by the tourist is 92 km.

Let's use a variable to represent the distance covered on the first day. We'll call it x.

On the first day, the tourist walked x km. On the second day, the tourist walked x - 2 km. On the third day, the tourist walked x - 4 km. On the fourth day, the tourist walked x - 6 km.

The sum of these distances should be equal to 92 km:

x + (x - 2) + (x - 4) + (x - 6) = 92

Simplifying the equation:

4x - 12 = 92

Adding 12 to both sides:

4x = 104

Dividing both sides by 4:

x = 26

Therefore, the distance covered by the tourist on the first day is 26 km.

Now, we can calculate the distance covered by the tourist on the last day:

Last day distance = x - 6 = 26 - 6 = 20 km

So, the tourist covered 20 km on the last day.
