Question

Два пешехода пошли одновременно навстречу друг другу из двух поселков и встретились через 3 ч.Расстояния между поселками 36,9 км.Найдите скорость каждого пешехода,если у одного она на 2 км/ч меньше,чем у другого.

Answer 1

1) 36,9 : 3 = 12,3 км/ч скорость первого
2) 12,3 - 2 = 10,3 км/ч скорость второго

Answer 2

расстояние делим на время (36.9 : 3 = 12.3) и от полученого ответа отнимаем 2 (12.3 - 2 = 10.3). Ответ скорость первого пеш. 10.3 км/ч., второго 12.3 км/ч.

Answer 3

Problem Analysis

We have two pedestrians walking towards each other from two different villages and they meet after 3 hours. The distance between the villages is 36.9 km. One pedestrian's speed is 2 km/h less than the other pedestrian's speed. We need to find the speed of each pedestrian.

Solution

Let's assume the speed of the slower pedestrian is x km/h. Then the speed of the faster pedestrian will be x + 2 km/h.

We can use the formula speed = distance / time to find the speeds of the pedestrians.

Calculation

- The slower pedestrian's speed: x km/h - The faster pedestrian's speed: x + 2 km/h - Time taken to meet: 3 hours - Distance between the villages: 36.9 km

Using the formula speed = distance / time, we can set up the following equations:

1. For the slower pedestrian: 36.9 = x * 3 2. For the faster pedestrian: 36.9 = (x + 2) * 3

Simplifying the equations:

1. 36.9 = 3x 2. 36.9 = 3x + 6

Solving the equations:

1. 3x = 36.9 - Dividing both sides by 3: x = 12.3

2. 3x + 6 = 36.9 - Subtracting 6 from both sides: 3x = 30.9 - Dividing both sides by 3: x = 10.3

Answer

Therefore, the speed of the slower pedestrian is 10.3 km/h and the speed of the faster pedestrian is 12.3 km/h.
