Tourists covered 36 km in 3 days, and the distances they covered are proportional to the numbers 4.3 and 2.

Tourists covered 36 km in 3 days, and the distances they covered are proportional to the numbers 4.3 and 2. How many kilometers have they covered in the last 2 days.

1. First, let’s calculate how many parts the whole path is divided into, if on the first, second and third days the path is related as 4: 3: 2. For this, these numerical ratios must be added:
4 + 3 + 2 = 7 + 2 = 9 parts.
2. Divide the length of the entire path into 9 parts and determine the value of one part:
36 km / 9 = 4 km.
3. Since one part is 4 km, we can find how long the path was covered on each day. First, let’s add the parts of the second and third days:
3 + 2 = 5.
4. Now we multiply the length of one part by 5 parts and get how far the tourists have traveled in the last two days:
5 * 4 = 20 km.
Answer: over the past two days, tourists have walked only 20 kilometers.
