Question

Из двух горныж аулов, расстояние между которыми 45км, одновременно навстречу друг другу выехали два путешествинника. Один ехал на осле со скоростью 4км/ч а другой- на амуле. Через 5ч они встретились. Найди скорость, с которой двигался путешествинник на амуле

Answer 1

45 : 5 = 9 км/ч - расстряние делим на время

Answer 2

Problem Analysis

Two travelers set off simultaneously from two mountain villages that are 45 km apart. One traveler rides a donkey at a speed of 4 km/h, while the other rides a mule. After 5 hours, they meet each other. We need to find the speed at which the traveler on the mule was moving.

Solution

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

Let's assume the speed of the traveler on the mule is x km/h.

The distance traveled by the traveler on the donkey is 4 km/h × 5 h = 20 km.

The distance traveled by the traveler on the mule is x km/h × 5 h = 5x km.

Since they meet each other after 5 hours, the sum of the distances traveled by both travelers should be equal to the total distance between the villages, which is 45 km.

So, we can write the equation: 20 km + 5x km = 45 km.

Simplifying the equation, we get: 5x km = 45 km - 20 km.

Simplifying further, we have: 5x km = 25 km.

Finally, dividing both sides of the equation by 5, we find: x km = 25 km / 5.

Therefore, the speed at which the traveler on the mule was moving is 5 km/h.

Answer

The traveler on the mule was moving at a speed of 5 km/h.

Explanation

The traveler on the donkey traveled a distance of 20 km in 5 hours at a speed of 4 km/h. The traveler on the mule traveled a distance of 5x km in 5 hours at a speed of x km/h. Since they met each other after 5 hours, the sum of their distances should be equal to the total distance between the villages, which is 45 km. By solving the equation, we find that the speed of the traveler on the mule was 5 km/h.
