Question

Из одного поселка по прямой дороги в двух противоположных направлениях одновременно вышли два пешехода.Скорость первого 4,6км/ч а второго на 0,92км/ч больше.Через сколько часов расстояние между пешеходами будет равно 20,24км?

Answer 1

1)4.6+0.92=5.52-скорость второго пешехода.

2)5.52+4.6=10.12-такое расстояние между пешеходами будет через 1 час.

3)20.24:10.12=2-через столько часов расстояние между пешеходами будет 20.24 км

Ответ:через 2 часа

Answer 2

Problem Analysis

We have two pedestrians walking in opposite directions from a village along a straight road. The first pedestrian has a speed of 4.6 km/h, while the second pedestrian has a speed that is 0.92 km/h faster. We need to determine how many hours it will take for the distance between the pedestrians to be 20.24 km.

Solution

Let's assume that the second pedestrian's speed is x km/h. Since the second pedestrian's speed is 0.92 km/h faster than the first pedestrian's speed, we can write the equation:

x = 4.6 + 0.92

Simplifying the equation, we find:

x = 5.52 km/h

Now, we can calculate the time it takes for the distance between the pedestrians to be 20.24 km. We can use the formula:

time = distance / relative speed

The relative speed is the sum of the speeds of the two pedestrians, which is 4.6 km/h + 5.52 km/h = 10.12 km/h.

Substituting the values into the formula, we get:

time = 20.24 km / 10.12 km/h

Simplifying the equation, we find:

time = 2 hours

Therefore, it will take 2 hours for the distance between the pedestrians to be 20.24 km.

Answer

It will take 2 hours for the distance between the two pedestrians to be 20.24 km.
