Question

Катер скорость которого 14,8 км в час,шёл 3ч по течению и 4ч против течения.Какой путь приодолел катер за всё это время,если скорость течения 2,3 км в час?СРОЧНО!!!! РЕШЕНИЕ ПО ДЕЙСТВИЯМ ПОЖАЛУЙСТА

Answer 1

(14.8+2.3)*3=51.3 км прошёл катер по течению.
((14.8-2.3)*4)+51.3=113.8 км прошёл катер всего.
Ответ:113.8 километров

Answer 2

1)14,8+2,3=17,1(км/ч)-шёл катер по течению
2)14,8-2,3=12,5(км/ч)-шёл катер против течения
3)17,1*3=51,3(км)-расстояние ,которое катер прошёл по течению
4)12,5*4=50(км)-расстояние ,которое катер прошёл против течения
5)51,3+50=101,3(км)-расстояние,которое прошёл катер
Ответ:101,3 км

Answer 3

Problem Analysis

We are given the speed of a boat, the time it traveled with the current, the time it traveled against the current, and the speed of the current. We need to find the total distance covered by the boat during this time.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's break down the problem into two parts: the distance covered with the current and the distance covered against the current.

1. Distance covered with the current: - Speed of the boat = 14.8 km/h - Time traveled with the current = 3 hours - Speed of the current = 2.3 km/h

Using the formula, the distance covered with the current can be calculated as: distance_with_current = (boat_speed + current_speed) × time_with_current

Substituting the given values: distance_with_current = (14.8 + 2.3) × 3

2. Distance covered against the current: - Speed of the boat = 14.8 km/h - Time traveled against the current = 4 hours - Speed of the current = 2.3 km/h

Using the formula, the distance covered against the current can be calculated as: distance_against_current = (boat_speed - current_speed) × time_against_current

Substituting the given values: distance_against_current = (14.8 - 2.3) × 4

3. Total distance covered: The total distance covered by the boat is the sum of the distances covered with and against the current: total_distance = distance_with_current + distance_against_current

Substituting the calculated values: total_distance = distance_with_current + distance_against_current

Now, let's calculate the distances.

Calculation

1. Distance covered with the current: distance_with_current = (14.8 + 2.3) × 3 = 17.1 × 3 = 51.3 km

2. Distance covered against the current: distance_against_current = (14.8 - 2.3) × 4 = 12.5 × 4 = 50 km

3. Total distance covered: total_distance = distance_with_current + distance_against_current = 51.3 + 50 = 101.3 km

Answer

The boat covered a total distance of 101.3 km during the given time.

Please note that the above solution assumes a constant speed of the boat and current throughout the entire journey.
