Question

ПОМОГИТЕ ПОЖАЛУЙСТА ЗАДАЧА 5 КЛАССА!!!!Путешественник идёт из одного города в другой 10 ч, а второй путешественник тот же путь проходит за 15 ч через сколько дней встретятся путешественники ,если выйдут одновременно навстречу друг другу из этих городов?

Answer 1

Примем расстояние между городами за 1 (единицу). Тогда:
1 : 10 = 1/10 - условная скорость одного путешественника.
1 : 15 = 1/15 - условная скорость другого путешественника.
1/10 + 1/15 = 1/6 - условная скорость сближения.
1 : 1/6 = 6 (дн)
Ответ: через 6 дней встретятся путешественники.

Problem Analysis

We have two travelers who are traveling from one city to another. The first traveler takes 10 hours to complete the journey, while the second traveler takes 15 hours. We need to determine how many days it will take for the travelers to meet if they start at the same time and walk towards each other.

Solution

To solve this problem, we can use the concept of relative speed. The relative speed of the two travelers is the sum of their individual speeds. We can calculate the relative speed by dividing the total distance between the two cities by the total time taken by both travelers.

Let's assume that the distance between the two cities is D.

The speed of the first traveler is given by: Speed1 = D / 10 (since the first traveler takes 10 hours to complete the journey).

The speed of the second traveler is given by: Speed2 = D / 15 (since the second traveler takes 15 hours to complete the journey).

The relative speed of the two travelers is: RelativeSpeed = Speed1 + Speed2.

To find the time it takes for the travelers to meet, we can divide the distance between the two cities by the relative speed: Time = D / RelativeSpeed.

Since we are given the time in hours, we need to convert it to days. We know that there are 24 hours in a day, so the number of days it takes for the travelers to meet is: Days = Time / 24.

Let's calculate the number of days it takes for the travelers to meet.

Calculation

Using the given information, we can calculate the number of days it takes for the travelers to meet.

The speed of the first traveler is: Speed1 = D / 10.

The speed of the second traveler is: Speed2 = D / 15.

The relative speed of the two travelers is: RelativeSpeed = Speed1 + Speed2.

The time it takes for the travelers to meet is: Time = D / RelativeSpeed.

The number of days it takes for the travelers to meet is: Days = Time / 24.

Let's calculate the values.

Speed1 = D / 10.

Speed2 = D / 15.

RelativeSpeed = Speed1 + Speed2.

Time = D / RelativeSpeed.

Days = Time / 24.

Answer

Based on the calculations, we can determine the number of days it takes for the travelers to meet. However, we need the value of the distance between the two cities (D) to provide an exact answer. Please provide the value of D so that we can calculate the number of days it takes for the travelers to meet.

Please note that the given search results did not provide the specific formula or calculation for this problem. However, the solution is based on the concept of relative speed, which is a fundamental concept in solving such problems.
