Question

два велосипедиста одновременно выехали с двух станций навстречу друг другу. расстояниемежду станциями 3 км290м.Скорость первого 130км ч второго на 25 км ч меньше.На каком расстоянии от каждой из станции произойдет встреча?

Answer 1

1)130-25=105(км\ч)-скорость 2

2)105+ 130=235(км\ч)-скорость сближения

3)3,29/235=0,014(ч)-время

4)130*0,014=1,82(км)-расстояние от первой

5)105*0,014=1,47(км)-расстояние от второй

Answer 2

130-25=105 (км/ч)-СКОРОСТЬ 2-го ВЕЛОСИПЕДИСТА

130+105=235(км/ч)-СКОРОСТЬ СБЛИЖЕНИЯ

3,290/235=0,014(ч)-время двмжения до встречи

130*0,014=1,82(км)-от 1 станции

105*0,014=1,47(км)-от 2 станции

 

Answer 3

Problem Analysis

We have two cyclists starting simultaneously from two different stations and moving towards each other. The distance between the stations is given as 3 km 290 m. The first cyclist has a speed of 130 km/h, while the second cyclist has a speed 25 km/h less than the first cyclist. We need to determine the distance from each station where the two cyclists will meet.

Solution

Let's denote the distance from the first station to the meeting point as 'x' km. Since the total distance between the stations is 3 km 290 m, the distance from the second station to the meeting point will be (3.290 - x) km.

We can use the formula: time = distance / speed to calculate the time taken by each cyclist to reach the meeting point.

For the first cyclist: - Distance = x km - Speed = 130 km/h - Time taken = x / 130 hours

For the second cyclist: - Distance = (3.290 - x) km - Speed = (130 - 25) km/h (since the second cyclist's speed is 25 km/h less than the first cyclist) - Time taken = (3.290 - x) / 105 hours

Since both cyclists start simultaneously, the time taken by both cyclists to reach the meeting point will be the same. Therefore, we can equate the two time expressions and solve for 'x'.

Let's calculate the value of 'x' using the given information.

Calculation

Equating the time expressions: x / 130 = (3.290 - x) / 105

Simplifying the equation: 105x = 130(3.290 - x) 105x = 427.7 - 130x 235x = 427.7 x = 427.7 / 235 x ≈ 1.82 km

Answer

The two cyclists will meet at a distance of approximately 1.82 km from the first station and at a distance of approximately (3.290 - 1.82) km = 1.47 km from the second station.

Please note that the above calculations are based on the given information and assumptions.
