Question

Собственная скорость катера 15,3 км/ч а скорость течения 2,4 км/ч.За 2 ч.катер по течению реки преодолел 30% расстояния между пристанями А и В.чему равно расстояние между пристанями А и В.

Answer 1

Расстояние сразу обозначаем за х.
Плыл по течению,значит складываем соб.скор.+скор.теч.
Составим уравнение(S=Vt):
0,3х\17,7=2
0,3х=35,4
х=118
Ответ:118

Answer 2

Given Information:

- The speed of the boat is 15.3 km/h. - The speed of the current is 2.4 km/h. - The boat traveled for 2 hours. - The boat covered 30% of the distance between the ports A and B.

Calculating the Distance:

To find the distance between ports A and B, we need to calculate the total distance covered by the boat in 2 hours. Since the boat traveled for 2 hours, we can calculate the distance using the formula:

Distance = Speed × Time

The boat's speed is 15.3 km/h, and it traveled for 2 hours, so the distance covered by the boat is:

Distance = 15.3 km/h × 2 hours

Let's calculate the distance covered by the boat:

Distance = 15.3 km/h × 2 hours = 30.6 km

Now, we know that the boat covered 30% of the distance between ports A and B. Let's denote the total distance between ports A and B as 'D'. According to the given information, the boat covered 30% of D. We can represent this as:

0.3D = 30.6 km

To find the total distance between ports A and B, we can solve this equation for D:

D = (30.6 km) / 0.3

Let's calculate the distance between ports A and B:

D = (30.6 km) / 0.3 = 102 km

Therefore, the distance between ports A and B is 102 km.

Answer:

The distance between ports A and B is 102 km.
