Question

Скорость катера 22 8/10 км/ч . Скорость реки в 6 раз меньше скорости катера. Какое расстояние проплывает катер за 3 часа?

Answer 1

22,8:6=3,8км/ч скорость реки
3*(22,8+3,8)=3*26,6=79,8км пройдет катер за 3часа по течению реки
3*(22,8-3,8)=3*19=57км пройдет катер за 3часа против течения

Answer 2

Calculation of Distance Traveled by the Boat

To calculate the distance traveled by the boat in 3 hours, we need to determine the speed of the boat and the speed of the river.

Given: - Speed of the boat: 22 8/10 km/h - Speed of the river: 6 times less than the speed of the boat

Let's calculate the speed of the river first.

The speed of the river is 6 times less than the speed of the boat. Therefore, the speed of the river can be calculated as follows:

Speed of the river = Speed of the boat / 6

Substituting the given value of the boat's speed into the equation:

Speed of the river = 22 8/10 km/h / 6

To simplify the calculation, let's convert the mixed fraction into an improper fraction:

Speed of the river = (22 * 10 + 8) / 10 km/h / 6

Speed of the river = (228/10) km/h / 6

Simplifying further:

Speed of the river = 38/5 km/h / 6

Now, let's calculate the distance traveled by the boat in 3 hours.

The distance traveled by the boat can be calculated using the formula:

Distance = Speed * Time

Substituting the values into the equation:

Distance = (22 8/10 km/h - 38/5 km/h / 6) * 3 hours

To simplify the calculation, let's convert the mixed fraction into an improper fraction:

Distance = ((22 * 10 + 8) / 10 km/h - 38/5 km/h / 6) * 3 hours

Distance = (228/10 km/h - 38/5 km/h / 6) * 3 hours

Simplifying further:

Distance = (228/10 km/h - 38/5 km/h / 6) * 3 hours

Now, let's calculate the distance:

Distance = (22.8 km/h - 7.6 km/h) * 3 hours

**Distance = 15.2 km/h * 3 hours
