Question

Задача От пристани одновременно в противоположных направлениях отошли два теплохода. Когда один из них прошёл 180 км со скоростью 30 км/ч, расстояние между теплоходами стало равным 348 км. С какой скоростью шёл другой теплоход ? Умоляю помогите мне !!!

Answer 1

348-180=168км расстояние которое прошел 2 
180\30=6 время в пути 
168\6=28км\ч скорость второго 

Answer 2

Problem Analysis

We have two ships that depart from a port simultaneously in opposite directions. One of the ships travels a distance of 180 km with a speed of 30 km/h. After this, the distance between the two ships is 348 km. We need to find the speed of the other ship.

Solution

Let's assume the speed of the other ship is x km/h.

The first ship travels a distance of 180 km with a speed of 30 km/h. Therefore, the time taken by the first ship is given by:

Time taken by the first ship = Distance / Speed = 180 km / 30 km/h = 6 hours

During this time, the second ship also travels for 6 hours at a speed of x km/h. Therefore, the distance traveled by the second ship is:

Distance traveled by the second ship = Speed * Time = x km/h * 6 hours = 6x km

Given that the distance between the two ships after the first ship has traveled 180 km is 348 km, we can set up the following equation:

Distance traveled by the second ship + Distance traveled by the first ship = Total distance between the ships

6x km + 180 km = 348 km

Simplifying the equation:

6x + 180 = 348

6x = 348 - 180

6x = 168

x = 168 / 6

x = 28

Therefore, the speed of the other ship is 28 km/h.

Answer

The other ship was traveling at a speed of 28 km/h.
