Answer 2

Calculation of Distance Covered by Tourists on the Third Day

To calculate the distance covered by the tourists on the third day, we need to analyze the information provided.

According to the given information: - On the first day, the group of tourists covered 18 km. - This distance is twice as much as the distance covered on the second day. - On the third day, the group covered a distance that is 6 km more than the distance covered on the second day.

Let's break down the information step by step:

1. Distance covered on the second day: - Let's assume the distance covered on the second day is x km. - According to the given information, the distance covered on the first day is twice as much as the distance covered on the second day. So, the distance covered on the first day is 2x km.

2. Distance covered on the third day: - The distance covered on the third day is 6 km more than the distance covered on the second day. - Therefore, the distance covered on the third day is x + 6 km.

Now, we can calculate the distance covered on the third day by substituting the value of x:

Distance covered on the third day = x + 6 km.

Please note that we don't have the exact value of x or the distance covered on the second day. Without that information, we cannot provide the exact distance covered on the third day.
