Question

Помогите катер по озеру прошёл расстояние в 52 км за 4 часа без остановок, а по реке против течения, скорость которого 3 км/ч, прошёл 30км за 4 часа, сделав при этом 1 остановку.Сколько времени длилась остановках

Answer 1

52 \ 4 = 13 км\ч скорость катера
13 - 3 = 10 км\ч  скорость катера против течения                                           30 \ 10 = 3 часа
4 - 3 = 1 час длилась остановка

Answer 2

Calculating Stoppage Time

To calculate the duration of the stoppage, we can use the information provided about the boat's speed and the distance traveled.

The boat traveled 30 km against the current in 4 hours, making 1 stop. To find the duration of the stoppage, we can use the formula: \[ \text{Total time} = \text{Time spent traveling} + \text{Stoppage time} \]

Given: - Distance traveled against the current: 30 km - Speed of the boat against the current: 3 km/h - Time taken to travel: 4 hours - Number of stops: 1

We can calculate the time spent traveling against the current using the formula: \[ \text{Time spent traveling} = \frac{\text{Distance}}{\text{Speed}} \]

Let's calculate the time spent traveling against the current: \[ \text{Time spent traveling} = \frac{30 \text{ km}}{3 \text{ km/h}} = 10 \text{ hours} \]

Now, we can use the total time formula to find the stoppage time: \[ \text{Total time} = 10 \text{ hours} + \text{Stoppage time} \] \[ 4 \text{ hours} = 10 \text{ hours} + \text{Stoppage time} \] \[ \text{Stoppage time} = 4 \text{ hours} - 10 \text{ hours} \] \[ \text{Stoppage time} = -6 \text{ hours} \]

It seems that the calculated stoppage time is negative, which doesn't make sense in this context. There might be a discrepancy in the provided information or calculations. Let's re-evaluate the given information and calculations to ensure accuracy.
