Question

Из двух посёлков удалённых на некоторое расстояние вышли одновременно и пошли в противоположном направлении два лыжника скорость одного из них была 14 км/ч скорость другого 12 км/ч через 2 часа расстояние между ними стало 80 км на каком расстоянии расположены поселки?Решите пожалуйста!!

Answer 1

14+12=26 км/час скорость удаления
26*2=52 км прошли за 2 часа
80-52=28 км между посёлками
=======================

Answer 2

14+12=26
26/2=13
13*80=1040

Answer 3

Problem Analysis

We have two skiers who start simultaneously from two villages and move in opposite directions. The speed of one skier is 14 km/h, and the speed of the other skier is 12 km/h. After 2 hours, the distance between them is 80 km. We need to find the distance between the two villages.

Solution

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

After 2 hours, the first skier will have covered a distance of 14 km/h * 2 h = 28 km from their starting village.

Similarly, the second skier will have covered a distance of 12 km/h * 2 h = 24 km from their starting village.

The total distance covered by both skiers is the sum of the distances covered by each skier, which is 28 km + 24 km = 52 km.

Since the total distance covered by both skiers is equal to the distance between the two villages, we can set up the following equation:

x = 52 km + 80 km

Simplifying the equation, we get:

x = 132 km

Therefore, the distance between the two villages is 132 km.

Answer

The distance between the two villages is 132 km.
