Question

Туристы прошли за три дня 48 км. В первый день они прошли 1/4 всего расстояния, а во второй день 5/9 остатка. сколько километров они прошли в третий день

Answer 1

48×1/4=12км в 1 день
48-12=36 км остаток
36×5/9=20км во 2 день
48-12-20=16 км в 3 день

Answer 2

Problem Analysis

The problem states that a group of tourists walked a total distance of 48 km in three days. On the first day, they walked 1/4 of the total distance, and on the second day, they walked 5/9 of the remaining distance. We need to determine how many kilometers they walked on the third day.

Solution

To solve this problem, we need to calculate the distances walked on the first and second days and then subtract them from the total distance to find the distance walked on the third day.

Let's calculate the distances step by step:

1. Calculate the distance walked on the first day: - The tourists walked 1/4 of the total distance on the first day. - Therefore, the distance walked on the first day is (1/4) * 48 km = 12 km.

2. Calculate the distance walked on the second day: - The tourists walked 5/9 of the remaining distance on the second day. - The remaining distance after the first day is (3/4) * 48 km = 36 km. - Therefore, the distance walked on the second day is (5/9) * 36 km = 20 km.

3. Calculate the distance walked on the third day: - To find the distance walked on the third day, we subtract the distances walked on the first and second days from the total distance. - The total distance is 48 km. - The distance walked on the first day is 12 km. - The distance walked on the second day is 20 km. - Therefore, the distance walked on the third day is 48 km - 12 km - 20 km = 16 km.

Answer

The tourists walked 16 km on the third day.

Verification

Let's verify the answer using the given information:

- The total distance walked by the tourists is 48 km. - On the first day, they walked 1/4 of the total distance, which is 12 km. - On the second day, they walked 5/9 of the remaining distance, which is 20 km. - Therefore, the total distance walked on the first and second days is 12 km + 20 km = 32 km. - The remaining distance after the first and second days is 48 km - 32 km = 16 km. - This matches the distance walked on the third day, which is 16 km.

The answer has been verified and is correct.
