Question

От 2 пристаней Одновременно навстречу друг другу отошли два катера и встретились через 5 часов Какой катер находился в пути до встречи дольше если скорость первого была 23 километров час а 2 27 километров час

Answer 1

5*23=115(км)-расстояние первого катера
5*27=135(км)-расстояние второго катера
Ответ:в пути дольше находился второй катер потому что прошёл 135 километров.

Answer 2

Problem Analysis

Two boats are moving towards each other from two different ports. The first boat has a speed of 23 kilometers per hour, while the second boat has a speed of 27 kilometers per hour. They meet each other after 5 hours. We need to determine which boat traveled for a longer distance before the meeting.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the first boat traveled for a time of t hours before the meeting. Therefore, the second boat traveled for a time of 5 - t hours before the meeting.

The distance traveled by the first boat can be calculated as 23 × t kilometers, and the distance traveled by the second boat can be calculated as 27 × (5 - t) kilometers.

Since the two boats meet each other, the sum of their distances should be equal to the total distance between the two ports. Let's calculate the total distance:

Total distance = distance traveled by the first boat + distance traveled by the second boat

Total distance = 23 × t + 27 × (5 - t) kilometers

We can simplify this equation to find the value of t:

Total distance = 23t + 135 - 27t

Simplifying further:

Total distance = -4t + 135

Since the total distance is constant, we can set it equal to the distance between the two ports. Let's assume the distance between the two ports is D kilometers.

-4t + 135 = D

Now, we can solve this equation to find the value of t:

4t = 135 - D

t = (135 - D) / 4

Therefore, the boat that traveled for a longer distance before the meeting is the one that corresponds to the larger value of t.

Let's calculate the value of t using the given speeds of the boats:

t = (135 - D) / 4

t = (135 - D) / 4

t = (135 - D) / 4

Calculation

To calculate the value of t, we need to know the distance between the two ports (D). Unfortunately, this information is not provided in the question. Please provide the distance between the two ports so that we can calculate the value of t and determine which boat traveled for a longer distance before the meeting.
