Question

два велосепедиста начали движение одновременно навстречу друг другу по шоссе между двумя городами. Скорость одного велесепедиста 220 м/мин, а друго 250 м/мин. На сколько приблизятся велосепедисты друг к другу через 30 мин?

Answer 1

Problem Analysis

We have two cyclists starting simultaneously and moving towards each other on a highway between two cities. The speed of one cyclist is 220 m/min, and the speed of the other cyclist is 250 m/min. We need to determine how close the cyclists will be to each other after 30 minutes.

Solution

To solve this problem, we can use the formula: Distance = Speed x Time.

Let's calculate the distance each cyclist will cover in 30 minutes:

- Cyclist 1: Speed = 220 m/min, Time = 30 min - Distance covered by Cyclist 1 = 220 m/min x 30 min = 6600 m

- Cyclist 2: Speed = 250 m/min, Time = 30 min - Distance covered by Cyclist 2 = 250 m/min x 30 min = 7500 m

Since the cyclists are moving towards each other, we need to add their distances to find out how close they will be to each other:

- Total distance covered by both cyclists = Distance covered by Cyclist 1 + Distance covered by Cyclist 2 - Total distance = 6600 m + 7500 m = 14100 m

Therefore, the cyclists will be approximately 14100 meters close to each other after 30 minutes.

Conclusion

After 30 minutes, the two cyclists will be approximately 14100 meters close to each other.
