Question

От двух пристаней отошли два теплохода навстречу друг другу навст. через 4 часа .скорость 36км.ч.вычесли скорость 2 теплохода если между прист. равно 264 км

Answer 1

36*4=144(км)-расстояние,которое пройдёт 1 теплоход за 4 часа
264-144=120(км)-расстояние,которое пройдёт 2 теплоход за 4 часа 
120:4=30(км/ч)-скорость 2 теплохода.
Ответ:30км/ч

Answer 2

Problem Analysis

We have two steamboats that depart from two different piers and head towards each other. After 4 hours, their distance between the piers is 264 km. We need to calculate the speed of each steamboat.

Solution

Let's assume the speed of the first steamboat is x km/h and the speed of the second steamboat is y km/h.

We know that the distance traveled by each steamboat is equal to the product of its speed and time. Therefore, the distance traveled by the first steamboat is x * 4 km and the distance traveled by the second steamboat is y * 4 km.

According to the problem, the sum of the distances traveled by both steamboats is equal to 264 km. So we can write the equation:

x * 4 + y * 4 = 264

Simplifying the equation, we get:

4x + 4y = 264

Dividing both sides of the equation by 4, we get:

x + y = 66

Now we have two equations: 1. x + y = 66 2. x = 36

We can substitute the value of x from the second equation into the first equation to solve for y:

36 + y = 66

Simplifying the equation, we get:

y = 66 - 36 = 30

Therefore, the speed of the first steamboat is 36 km/h and the speed of the second steamboat is 30 km/h.

Answer

The speed of the first steamboat is 36 km/h and the speed of the second steamboat is 30 km/h.
