Question

Решите две задачи из двух поселков , расстояние между которыми 250 км, одновременно в противоположных направлениях вышли два мотоциклиста скорость первого мотоциклиста 85 км\ч ,второго 95 км\ч .какое расстояние будет между ними через 2 часа?из двух сел , расстояние между которыми 90 км, одновременно в противоположныхнаправлениях вышли два велосипедиста скорость первого велосипедиста 10 км\ч ,второго 8 км\ч .какое расстояние будет между ними через 3 часа?

Answer 1

№1
1) 85+95=180 км/ч - скорость удаления
2) 180·2=360 км - проехали два мотоциклиста за 2ч.
3) 360+250=610км - расстояние между мотоциклистами через 2ч.
№2
1) 10+8=18км/ч - скорость удаления
2) 18·3=54км - проехали за 3ч. два велосипедиста
3) 90+54=144км - расстояние между велосипедистами через 3ч.

Answer 2

1)задача
250+(85+95)·2=610км-будет между ними через 2 часа
2)задача
90+(10+8)·3=144км-будет между ними через 3 часа

Answer 3

Problem 1: Two Motorcyclists

To solve this problem, we need to find the distance between two motorcyclists who are traveling in opposite directions at different speeds. The distance between the two towns is 250 km, and the speeds of the motorcyclists are 85 km/h and 95 km/h.

We can use the formula: distance = speed × time.

Let's calculate the distance between the two motorcyclists after 2 hours.

Motorcyclist 1: - Speed: 85 km/h - Time: 2 hours - Distance traveled by Motorcyclist 1: 85 km/h × 2 hours = 170 km

Motorcyclist 2: - Speed: 95 km/h - Time: 2 hours - Distance traveled by Motorcyclist 2: 95 km/h × 2 hours = 190 km

The total distance between the two motorcyclists after 2 hours is the sum of the distances traveled by each motorcyclist: 170 km + 190 km = 360 km.

Therefore, the distance between the two motorcyclists after 2 hours is 360 km.

Problem 2: Two Bicyclists

In this problem, we have two bicyclists traveling in opposite directions at different speeds. The distance between the two villages is 90 km, and the speeds of the bicyclists are 10 km/h and 8 km/h.

Using the same formula, distance = speed × time, let's calculate the distance between the two bicyclists after 3 hours.

Bicyclist 1: - Speed: 10 km/h - Time: 3 hours - Distance traveled by Bicyclist 1: 10 km/h × 3 hours = 30 km

Bicyclist 2: - Speed: 8 km/h - Time: 3 hours - Distance traveled by Bicyclist 2: 8 km/h × 3 hours = 24 km

The total distance between the two bicyclists after 3 hours is the sum of the distances traveled by each bicyclist: 30 km + 24 km = 54 km.

Therefore, the distance between the two bicyclists after 3 hours is 54 km.

I hope this helps! Let me know if you have any further questions.
