Question

Два велосипедиста выехали одновременно навстречу друг другу Из двух пунктов расстояние между ними которыми 36 километров скорость первого 10 километров час а второго 8 километров в час через сколько часов они встретятся?

Answer 1

10+8=18 км/час скорость сближения
36:18=2 час

Answer 2

Problem Analysis

We have two cyclists starting simultaneously from two different points and moving towards each other. The distance between the two points is 36 kilometers. The first cyclist has a speed of 10 kilometers per hour, while the second cyclist has a speed of 8 kilometers per hour. We need to determine how many hours it will take for them to meet.

Solution

To solve this problem, we can use the formula: time = distance / speed. We can calculate the time it takes for each cyclist to cover the distance between them, and the sum of these times will give us the total time it takes for them to meet.

Let's calculate the time it takes for the first cyclist to cover the distance: - Distance = 36 kilometers - Speed = 10 kilometers per hour - Time = Distance / Speed = 36 / 10 = 3.6 hours

Now, let's calculate the time it takes for the second cyclist to cover the distance: - Distance = 36 kilometers - Speed = 8 kilometers per hour - Time = Distance / Speed = 36 / 8 = 4.5 hours

The total time it takes for them to meet is the sum of these two times: - Total Time = 3.6 hours + 4.5 hours = 8.1 hours

Therefore, it will take them approximately 8.1 hours to meet.

Answer

The two cyclists will meet approximately 8.1 hours after they start their journey.
