Question

Задача. Помогите пожалуйста, срочно нужно. От пристани Марьино к пристани Алёшино отправился теплоход со скоростью 24 км / ч, а за 9 ч. до него в этом же направлении вышел буксир с баржами со скоростью 8 км / ч, который прибыл в Алёшино на 15 ч. позже теплохода. Найди расстояние между пристанями.

Answer 1

Пусть х км расстояние между пристанями
х/8 - шёл буксир от пристани Марьино к пристани Алёшино,
х/24 шёл теплоход от пристани Марьино к пристани Алёшино. Составим ур-ие:х/8 - х/24 = 15+9 3х/24 -х/24 = 24 2х/24 = 24 х/12 =24 х = 12*24 х= 288 Ответ : расстояние между пристанями 288 км

Answer 2

Task: Finding the distance between two ports

To find the distance between the Mar'ino port and the Al'yoshino port, we can use the formula:

Distance = Speed x Time

Let's calculate the distance step by step.

Given information: - Speed of the ship = 24 km/h - Speed of the tugboat with barges = 8 km/h - Time taken by the tugboat to reach Al'yoshino = 15 hours later than the ship - Time taken by the ship to reach Al'yoshino = 9 hours

First, let's calculate the distance covered by the tugboat in 15 hours.

Distance covered by the tugboat = Speed x Time Distance covered by the tugboat = 8 km/h x 15 hours

Using this information, we can calculate the distance covered by the tugboat.

Next, let's calculate the distance covered by the ship in 9 hours.

Distance covered by the ship = Speed x Time Distance covered by the ship = 24 km/h x 9 hours

Using this information, we can calculate the distance covered by the ship.

Finally, to find the total distance between the two ports, we need to add the distances covered by the tugboat and the ship.

Total distance = Distance covered by the tugboat + Distance covered by the ship

Let's calculate the distances and find the total distance between the Mar'ino port and the Al'yoshino port.
