Question

Решение задачи двигаясь против течения реки расстояние 60 километров Теплоход проходит за 4 часа Какова скорость течения реки если собственная скорость теплохода 16 километров в час

Answer 1

1) 60:4 = 15 км/ч скорость теплохода против течения реки
2) 16-15=1 км/ч скорость течения реки

Answer 2

Мне кажится скорость течения 5 км в час

Answer 3

Problem Analysis

We are given the following information: - The distance traveled against the current of a river is 60 kilometers. - The time taken to travel this distance is 4 hours. - The speed of the boat is 16 kilometers per hour.

We need to find the speed of the river current.

Solution

Let's assume the speed of the river current is x kilometers per hour.

The effective speed of the boat against the current can be calculated using the formula:

Effective speed = Boat speed - Current speed

In this case, the effective speed is 16 - x kilometers per hour.

We can use the formula:

Distance = Speed × Time

to calculate the distance traveled against the current:

60 = (16 - x) × 4

Simplifying the equation:

60 = 64 - 4x

Rearranging the equation:

4x = 64 - 60

4x = 4
