Question

Реши задачу От пристани Марьино к пристани Алёшино отправился теплоход со скоростью 24 км/ч, а за 24 часа до него в этом же направлении вышел буксир с баржами со скоростью 8 км/ч. Найди расстояние между пристанями , если теплоход и буксир прибыли к пристани Алёшино одновременно

Answer 1

Решение: 1) 24-8=16 кмчас -разница скоростей теплохода и буксира

2) 24*8=192 км - прошел буксир до момента отплытия теплохода

3) 192=12 часов - за столько теплоход дойдет до Алешино

4) 12*24=288 км - расстояние между пристанями

Ответ: 288 км 

Answer 2

To find the distance between the Mar'ino and Alyoshino ports, we can use the formula:

Distance = Speed x Time

Let's calculate the time it took for both the ship and the tugboat to reach the Alyoshino port.

The ship's speed is given as 24 km/h, and the time it took to reach the Alyoshino port is not specified. However, we know that the ship and the tugboat arrived at the port simultaneously. This means that the time it took for both of them to reach the port is the same.

Let's assume that the time taken by both the ship and the tugboat to reach the port is 't' hours.

Using the formula, we can write the equation:

Distance covered by the ship = Distance covered by the tugboat

24t = 8 x 24

Simplifying the equation:

24t = 192

Dividing both sides of the equation by 24:

t = 8

So, it took 8 hours for both the ship and the tugboat to reach the Alyoshino port.

Now, let's calculate the distance between the Mar'ino and Alyoshino ports using the ship's speed and the time taken:

Distance = Speed x Time

Distance = 24 km/h x 8 h

Distance = 192 km

Therefore, the distance between the Mar'ino and Alyoshino ports is 192 km.
