Question

От 2 пристаней Одновременно навстречу друг другу вышли две моторные лодки Скорость первой лодки 22 км ч скорость 2 на 3 км час больше лодки встретились через 4 часа Каково расстояние между пристанями

Answer 1

1) 22+3=25 (км/ч) скорость второй лодки.
2) 22+25=47 (км/ч) скорость сближения двух лодок.
3) 47×4=188 (км) расстояние между пристанями.
Ответ. 188км.

Answer 2

22+3=25 (км/ч) скорость второй
22*4= 88 (км) расстояние которое прошла 1 лодка
25*4=100 (км) расстояние которое прошла 2 лодка
100+88=188 (км) расстояние между пристонями

Answer 3

Problem Analysis

We have two motorboats that start simultaneously from two different piers and are moving towards each other. The speed of the first boat is 22 km/h, and the speed of the second boat is 3 km/h faster than the speed of the first boat. They meet after 4 hours. We need to find the distance between the piers.

Solution

Let's assume that the speed of the second boat is x km/h. Since the speed of the second boat is 3 km/h faster than the speed of the first boat, we can write the equation:

Speed of the second boat = Speed of the first boat + 3

Now, let's calculate the distance traveled by each boat in 4 hours:

Distance traveled by the first boat = Speed of the first boat × Time = 22 km/h × 4 h = 88 km

Distance traveled by the second boat = Speed of the second boat × Time = (22 km/h + 3 km/h) × 4 h = 100 km

Since the boats meet each other, the sum of the distances traveled by both boats should be equal to the distance between the piers. Let's denote the distance between the piers as D:

Distance traveled by the first boat + Distance traveled by the second boat = D

88 km + 100 km = D

D = 188 km

Therefore, the distance between the piers is 188 km.

Answer

The distance between the two piers is 188 km.
