Question

Помогите пж решить задачу: две моторные лодки одновременно отправляются навстречу друг другу от 2 пристаней расстояние между которыми 88 км одна из них скорости 24 км в час скорость другой на 4 километров меньше. Через сколько часов они встречаются.

Answer 1

Скорость одной 24 второй 20 минус 4 равно 20 км ч
т.к. они двигались навстречу то найдём их скорость сближения 20+24=44км ч
88÷44=2часа
Ответ:2 часа

Answer 2

1) 24-4=20 (км/ч) скорость 2-ой лодки
2) 20+24=44 (км) скорость двух лодок
3) 88 : 44=2 (ч)
Ответ : через 2 часа лодки встретятся 

Answer 3

Problem Analysis

We have two motorboats traveling towards each other from two different docks. The distance between the docks is 88 km. One boat is traveling at a speed of 24 km/h, while the other boat is traveling at a speed 4 km/h slower. We need to determine how many hours it will take for the boats to meet.

Solution

Let's denote the speed of the slower boat as x km/h. Since the faster boat is traveling at a speed of 24 km/h, the speed of the slower boat can be expressed as (24 - 4) km/h, which simplifies to 20 km/h.

To find the time it takes for the boats to meet, we can use the formula:

time = distance / relative speed

The relative speed of the two boats is the sum of their speeds, which is (24 + 20) km/h, or 44 km/h.

Substituting the values into the formula, we get:

time = 88 km / 44 km/h

Simplifying, we find that it will take 2 hours for the boats to meet.

Therefore, the two motorboats will meet after 2 hours.

Answer

The two motorboats will meet after 2 hours.
