Question

Из двух посёлков одновременно на встречу друг другу выехали 2 автомобиля. Один ехал со скоростью 53км/ч и проехал до встречи 212 км. определи расстояние между поселками если скорость второго была 48км/ч?

Answer 1

1) 212:53=4(ч)- двигались до встречи

2)48*4=192(км)- второй автомоболист за 4 часа

3)192+212=404(км)

Ответ: Расстояние между посёлками 404 км

Answer 2

Problem Analysis

We are given that two cars start simultaneously from two different villages and travel towards each other. The first car travels at a speed of 53 km/h and covers a distance of 212 km before they meet. We need to determine the distance between the two villages if the second car is traveling at a speed of 48 km/h.

Solution

Let's assume the distance between the two villages is d km.

The time taken by the first car to cover the distance is given by: time = distance / speed = 212 km / 53 km/h = 4 hours.

Similarly, the time taken by the second car to cover the distance is given by: time = distance / speed = d km / 48 km/h = d/48 hours.

Since both cars started simultaneously, they traveled for the same amount of time. Therefore, we can equate the times taken by both cars and solve for the distance between the villages:

4 hours = d/48 hours.

To solve for d, we can cross-multiply and solve the equation:

4 * 48 = d.

Calculating the value of d:

d = 192 km.

Therefore, the distance between the two villages is 192 km.

Answer

The distance between the two villages is 192 km.
