1)5*1,4=7 (ч) проедет второй
Ответ: второй

Answer 2

Problem 1: Иван-Царевич's Journey

To solve this problem, we need to calculate the total distance Ivan Tsarevich traveled in three days. Let's break down the information given:

- On the first day, Ivan Tsarevich traveled 7/19 of the total distance. - On the second day, he traveled 55% of the remaining distance. - On the third day, he traveled the remaining 108 km.

To find the total distance, we'll work backward from the third day to the first day.

Let's start by calculating the distance traveled on the third day.

Day 3:

Ivan Tsarevich traveled the remaining 108 km.

Day 2:

On the second day, Ivan Tsarevich traveled 55% of the remaining distance. To find the remaining distance, we subtract the distance traveled on the third day from the total remaining distance.

Let's denote the total remaining distance after the first day as D1.

The distance traveled on the second day is 0.55 * D1.

Day 1:

On the first day, Ivan Tsarevich traveled 7/19 of the total distance. To find the total distance, we need to find the remaining distance after the second day.

Let's denote the total remaining distance after the second day as D2.

The distance traveled on the first day is 7/19 * D2.

Now, we can calculate the total distance traveled by summing up the distances traveled on each day.

Total Distance:

The total distance traveled by Ivan Tsarevich in three days is the sum of the distances traveled on each day: (7/19 * D2) + (0.55 * D1) + 108 km.

To find the value of D2 and D1, we need additional information about the distances. Could you please provide the distances between the Tridevyatoye Tsarstvo and Tridesyatoe Gosudarstvo?
