Question

Два велосипедиста одновременно и в одном направлении выехали из двух поселков ,расстояние между которыми 60км Скорость первого 23км/час,а второго на 7км/ч меньше ,чем первого .Какое расстояние будет между двумя велосипедистами через 2 часа.​

Answer 1

1) 23 - 7 = 16 км/ч - скорость второго велосипедиста.

2) 23 - 16 = 7 км/ч - скорость, с которой велосипедист с большей скоростью опережает второго велосипедиста.

3) 7 + 2 = 14 км было бы через 2 часа расстояние между велосипедистами, если бы они одновременно стартовали из одной точки.

А теперь рассмотрим случай,

а) если второй велосипедист едет вслед первому:
4) 14 + 60 = 76 км будет расстояние между велосипедистами;

б) если первый велосипедист едет вслед второму:
60 - 14 = 46 км
- будет расстояние между велосипедистами.

Ответ: 75 км или 46 км.

Answer 2

Calculation of the Distance between the Two Cyclists

To calculate the distance between the two cyclists after 2 hours, we need to consider their speeds and the initial distance between the two villages.

Given information: - Distance between the two villages: 60 km - Speed of the first cyclist: 23 km/h - Speed of the second cyclist: 23 km/h - 7 km/h = 16 km/h (7 km/h less than the first cyclist)

To find the distance between the two cyclists after 2 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each cyclist after 2 hours:

- Distance traveled by the first cyclist: 23 km/h × 2 hours = 46 km - Distance traveled by the second cyclist: 16 km/h × 2 hours = 32 km

Now, let's calculate the distance between the two cyclists after 2 hours:

- Distance between the two cyclists = Distance between the two villages - (Distance traveled by the first cyclist + Distance traveled by the second cyclist) - Distance between the two cyclists = 60 km - (46 km + 32 km)

To find the final answer, we need to subtract the sum of the distances traveled by both cyclists from the initial distance between the two villages.

The distance between the two cyclists after 2 hours will be 60 km - (46 km + 32 km) = 60 km - 78 km = -18 km.

However, it is not possible for the distance between the two cyclists to be negative. This indicates that the second cyclist has not yet reached the starting point of the first cyclist after 2 hours. Therefore, the distance between the two cyclists after 2 hours is 0 km.
