Answer 2

To find out how many kilometers the tourists walked over the course of 4 days, we need to add up the distances they walked each day.

On the first day, they walked 10 8/12 km. On the second day, they walked 11 18/25 km. On the third day, they walked 9 4/12 km.

To add these distances together, we need to convert all the fractions to a common denominator. In this case, the common denominator is 12.

Converting the fractions: - 8/12 = 2/3 - 18/25 = 8/15 - 4/12 = 1/3

Now we can add the distances:

10 2/3 km + 11 8/15 km + 9 1/3 km

To add the whole numbers, we simply add them:

10 + 11 + 9 = 30

Now let's add the fractions:

2/3 + 8/15 + 1/3

To add fractions, we need to find a common denominator. In this case, the common denominator is 15.

Converting the fractions: - 2/3 = 10/15 - 1/3 = 5/15

Now we can add the fractions:

10/15 + 8/15 + 5/15 = 23/15

So the total distance the tourists walked over the course of 4 days is:

30 km + 23/15 km

To convert the fraction to a mixed number, we divide the numerator (23) by the denominator (15):

23 ÷ 15 = 1 remainder 8

Therefore, the total distance the tourists walked over the course of 4 days is approximately:

31 8/15 km.

Please note that this is an approximate value and may be rounded to the nearest decimal place.
