Question

От 2 пристаней отошли Одновременно навстречу друг другу катер и лодка они встретились через 5 часов скорость лодки 12 километров час а скорость катера в 5 раз больше Найди расстояние между пристанями пристанями

Answer 1

Общая скорость равна: 12+5*12=72 км/ч
Расстояние равно: 72 км/ч * 5 ч = 360 км
Ответ: 360 км

Answer 2

Problem Analysis

We are given that a boat and a motorboat set off simultaneously from two piers and meet after 5 hours. The speed of the boat is 12 kilometers per hour, and the speed of the motorboat is 5 times greater than that of the boat. We need to find the distance between the piers.

Solution

Let's assume the distance between the piers is d kilometers.

The boat's speed is 12 kilometers per hour, so in 5 hours, it will travel a distance of 12 * 5 = 60 kilometers.

The speed of the motorboat is 5 times greater than that of the boat, so its speed is 12 * 5 = 60 kilometers per hour. In 5 hours, it will also travel a distance of 60 * 5 = 300 kilometers.

Since the boat and motorboat meet after 5 hours, the total distance they travel is equal to the distance between the piers. Therefore, we can set up the following equation:

d = 60 + 300

Simplifying the equation, we find:

d = 360

Therefore, the distance between the piers is 360 kilometers.

Answer

The distance between the two piers is 360 kilometers.
