Question

Из 2 посёлков расстояние между которыми 27 километров вышли Одновременно навстречу друг другу два пешехода скорость первого пешехода 5 километров в час а скорость второго 4 километров в час через сколько часов пешиходы встретиться

Answer 1

1) 4+5= 9 (км/ч) скорость сближения пешеходов
2) 27:9= 3 (ч.)  время, через которое пешеходы встретятся

Ответ: через 3 часа  пешеходы встретятся.

Answer 2

S-27км
V1-5км/ч
V2-4км/ч
t-?ч.
Решение:
t=S÷V
1)5+4=9(км/ч)-расстояние которое они проходят за час.
2) 27÷9=3(ч.)-время.
Ответ:через 3 часа они встретятся.

Answer 3

Problem Analysis

We have two pedestrians walking towards each other from two villages that are 27 kilometers apart. The first pedestrian has a speed of 5 kilometers per hour, while the second pedestrian has a speed of 4 kilometers per hour. We need to determine how many hours it will take for the pedestrians to meet.

Solution

To find the time it takes for the pedestrians to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the two pedestrians.

Let's calculate the time it takes for the pedestrians to meet.

Calculation

The distance between the two villages is 27 kilometers. The speed of the first pedestrian is 5 kilometers per hour. The speed of the second pedestrian is 4 kilometers per hour.

The relative speed of the two pedestrians is 5 + 4 = 9 kilometers per hour.

Using the formula, we can calculate the time it takes for the pedestrians to meet:

Time = Distance / Relative Speed

Time = 27 kilometers / 9 kilometers per hour

Time = 3 hours

Answer

The pedestrians will meet after 3 hours.
