Question

Туристы были в пути три дня. В первый день они прошли 18 км, во второй на 3 км больше, в третий день в 3 раза меньше, чем в первый и во второй день вместе. Какое расстояние прошли туристы за 3 дня.

Answer 1

1) 18 + 3 = 21 (км) - прошли во  второй день
2) 18 + 21 = 39 (км) - прошли в первый и второй дни
3) 39 : 3 = 13 (км) - прошли в третий день
4) 39 + 13 = 52 (км) - прошли за три дня
Ответ: 52 км.

Answer 2

Calculating the Distance Traveled by Tourists

To calculate the total distance traveled by the tourists over the three days, we can follow these steps:

1. Distance on the First Day: - On the first day, the tourists walked 18 km.

2. Distance on the Second Day: - On the second day, they walked 3 km more than the first day, which is 18 km + 3 km = 21 km.

3. Distance on the Third Day: - On the third day, they walked one-third of the combined distance covered on the first and second days.

4. Calculating the Total Distance: - We will calculate the total distance traveled by adding the distances covered on each day.

Solution

1. Distance on the First Day: - 18 km.

2. Distance on the Second Day: - 21 km (18 km + 3 km).

3. Distance on the Third Day: - One-third of the combined distance on the first and second days. - Combined distance on the first and second days: 18 km + 21 km = 39 km. - One-third of 39 km: 39 km / 3 = 13 km.

4. Total Distance Traveled: - Adding the distances covered on each day: 18 km + 21 km + 13 km = 52 km.

Therefore, the tourists traveled a total distance of 52 km over the three days.
