Question

Два велосипедиста выехали из двух пунктов навстречу другу другу.Когда первый проехал 1км180м,второй проехал 820м.На какое расстояние сблизились велосипедисты?

Answer 1

1 км 180 м = 1180 м
1180+820= 200(м)
Ответ: велосипедисты сблизились на 2000 м (2км)

Answer 2

1км180м = 1180м
1180 + 820 = 2000м
2000м = 2км
ответ: на 2км

Answer 3

Calculating the Distance Between Cyclists

To find the distance at which the cyclists approached each other, we can use the concept of relative speed. The relative speed is the combined speed at which the two cyclists are approaching each other.

First, let's calculate the distance at which the cyclists approached each other.

The first cyclist traveled 1 km 180 m, which is equivalent to 1180 m, and the second cyclist traveled 820 m.

Now, we can calculate the distance at which the cyclists approached each other using the following formula:

Distance = Speed × Time

The time taken by both cyclists to cover their respective distances is the same, as they started at the same time and met each other. Therefore, we can use the relative speed to calculate the distance at which they approached each other.

Calculating Relative Speed

The relative speed of the two cyclists is the sum of their individual speeds, as they are moving towards each other.

Let's assume the speed of the first cyclist is v1 and the speed of the second cyclist is v2.

Relative Speed Formula

The relative speed formula for two objects moving towards each other is:

Relative Speed = Speed of first object + Speed of second object

Applying the Relative Speed Formula

Now, we can apply the relative speed formula to find the distance at which the cyclists approached each other.

Given: - Distance covered by the first cyclist = 1180 m - Distance covered by the second cyclist = 820 m

Let's calculate the relative speed and then use it to find the distance at which the cyclists approached each other.

Calculation

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

Let's assume the speed of the first cyclist is v1 and the speed of the second cyclist is v2.

The relative speed formula is: Relative Speed = v1 + v2

Now, we can proceed with the calculation.
