Question

Великий шёлковый путь связывал китай с чёрным иореи . из караван-сараев расстояние между которыми 77 км вышли одновременно навстречу друг другу два купеческих каравана . через 7 ч они встретились . Сколько каравана идущего из китая 6 км . Сколько км прошёл до места встречи караван идущий в китай . поиагите пожалуста

Answer 1

1 способ (решение уравнением)

6 км/ч - скорость одного каравана, х км/ч - скорость другого каравана

S = v * t - формула пути    S = 77 км     v = (6 + х) км/ч     t = 7 ч

(6 + х) * 7 = 77

6 + х = 77 : 7 

6 + х = 11

х = 11 - 6

х = 5 (км/ч) - скорость другого каравана

6 * 7 = 42 (км) - прошёл до встречи один караван (из Китая)

5 * 7 = 35 (км) - прошёл до встречи другой караван (в Китай)

Ответ: караван, идущий в Китай, прошёл до места встречи 35 км.

2 способ (решение по действиям)

1) 6 * 7 = 42 (км) - прошёл до встречи караван, идущий из Китая;

2) 77 - 42 = 35 (км) - прошёл до встречи караван, идущий в Китай;

3) 35 : 7 = 5 (км/ч) - скорость каравана, идущего в Китай.

Answer 2

The Great Silk Road and the Caravanserais

The Great Silk Road was an ancient network of trade routes that connected China with the Black Sea region, including the area around the Black Sea. It facilitated the exchange of goods, ideas, and cultures between the East and the West. Along the Silk Road, caravanserais were established as resting places for merchants and their caravans.

Caravanserais were strategically located at regular intervals along the Silk Road to provide shelter, food, and other necessities for travelers. These caravanserais played a crucial role in facilitating trade and communication between different regions. One such example is the caravanserais located 77 kilometers apart, which were encountered simultaneously by two merchant caravans traveling in opposite directions.

Calculation of the Distance Traveled

Let's calculate the distance traveled by the caravan coming from China and the distance traveled by the caravan heading towards China before they met.

Given: - Distance between the caravanserais: 77 km - Time taken for the caravans to meet: 7 hours

To find the distance traveled by the caravan coming from China, we can use the formula:

Distance = Speed × Time

Let's assume the speed of the caravan coming from China is x km/h.

The distance traveled by the caravan coming from China is 6 km. Therefore, we can set up the equation:

6 km = x km/h × 7 hours

Simplifying the equation, we get:

x km/h = 6 km / 7 hours

Now, let's calculate the speed of the caravan coming from China:

x km/h = 0.857 km/h

Since we know the speed, we can calculate the distance traveled by the caravan heading towards China before they met. Using the formula:

Distance = Speed × Time

Let's assume the speed of the caravan heading towards China is y km/h.

The time taken for the caravans to meet is 7 hours. Therefore, we can set up the equation:

77 km = y km/h × 7 hours

Simplifying the equation, we get:

y km/h = 77 km / 7 hours

Now, let's calculate the speed of the caravan heading towards China:

y km/h = 11 km/h

Therefore, the caravan coming from China traveled 0.857 km before they met, and the caravan heading towards China traveled 77 km - 0.857 km = 76.143 km before they met.

Summary:

- The caravan coming from China traveled 0.857 km before they met the other caravan. - The caravan heading towards China traveled 76.143 km before they met the other caravan.

Please note that the calculations provided are based on the given information and assumptions made.
