Question

Решительно задачу, пожалуйста! Собственная скорость катера 22,8 км/ч. Скорость течения реки в 6 раз меньше, чем скорость катера. Какое расстояние проплывает катер по течению реки 3 ч.

Answer 1

22,8:6=3,8(км/ч) - скорость течения
22,8+3,8=26,6(км/ч) - скорость катера по течению
26,6*3=79,8(км)
Ответ: 79,8 км

Answer 2

Problem Analysis

To solve this problem, we need to determine the distance the boat travels downstream in 3 hours, given that the boat's speed is 22.8 km/h and the river's current is 6 times slower than the boat's speed.

Calculation

Let's calculate the speed of the river's current first. Since the river's current is 6 times slower than the boat's speed, we can calculate it as follows:

Speed of the river's current = (Speed of the boat) / 6

Substituting the given value, we have:

Speed of the river's current = 22.8 km/h / 6 = 3.8 km/h

Now, we can calculate the distance the boat travels downstream in 3 hours using the formula:

Distance = Speed × Time

Substituting the values, we have:

Distance = (Speed of the boat + Speed of the river's current) × Time

Distance = (22.8 km/h + 3.8 km/h) × 3 hours

Distance = 26.6 km/h × 3 hours

Distance = 79.8 km

Answer

The boat will travel a distance of 79.8 km downstream in 3 hours.
