Question

Перед перерывом в лагере ученики шли со скоростью 4,5 км / ч, а на обратном пути в лагерь они потратили еще 15 минут и пошли со скоростью 4 км / ч. Как далеко от лагеря они сделали перерыв?​

Answer 1

Ответ:

Пошаговое объяснение:

x - время затраченное на путь до перерыва

x + 1/4 -время затраченное на обратный путь

4,5x = 4*(x + 1/4)

4,5x = 4x + 1

4,5x - 4x = 1

0,5x = 1

x = 1:0,5

x = 2часа время затраченное на путь до перерыва

4,5*2 = 9км от лагеря они сделали перерыв

Answer 2

Calculation of the Distance

To calculate the distance from the campsite where the students took a break, we need to determine the time it took for them to reach the break point and the time it took for them to return to the campsite.

Let's start by calculating the time it took for the students to reach the break point.

Given: - Speed on the way to the break point: 4.5 km/h

We can use the formula: distance = speed × time.

Let's assume the time taken to reach the break point is t hours.

Therefore, the distance covered on the way to the break point is 4.5t kilometers.

Next, let's calculate the time it took for the students to return to the campsite.

Given: - Speed on the way back to the campsite: 4 km/h - Additional time spent on the return journey: 15 minutes

To convert the additional time spent to hours, we divide 15 minutes by 60: 15/60 = 0.25 hours.

Let's assume the time taken to return to the campsite is t + 0.25 hours.

Therefore, the distance covered on the way back to the campsite is 4(t + 0.25) kilometers.

To find the total distance covered, we add the distances covered on the way to the break point and on the way back to the campsite.

Total distance = distance to the break point + distance back to the campsite Total distance = 4.5t + 4(t + 0.25) kilometers

Now, we need to find the value of t that satisfies the given conditions.

Unfortunately, the provided search results do not provide any relevant information to directly calculate the distance. However, we can still proceed with the calculations based on the given information.

Please note that without additional information or context, we cannot determine the exact distance from the campsite where the students took a break.
