Question

Из двух посёлков навстречу друг другу одновременно выехали два велосипедиста скорость одного 12 км час ,другого 14км час . Найди расстояние между поселками если велосипедисты встретились через 3 часа

Answer 1

1)12умножить на 3=36
2)14умножить на 3=42
3)42+36=78

Answer 2

12 + 14 = 26 км/ч - скорость сближения
26 х 3 = 78 км - между поселками

Answer 3

Problem Analysis

We are given that two cyclists start simultaneously from two villages and travel towards each other. The speed of one cyclist is 12 km/h, and the speed of the other cyclist is 14 km/h. We need to find the distance between the villages when the cyclists meet after 3 hours.

Solution

To find the distance between the villages, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each cyclist and then find the total distance between the villages.

1. Distance traveled by the first cyclist: - Speed of the first cyclist = 12 km/h - Time = 3 hours - Distance = Speed × Time = 12 km/h × 3 hours = 36 km

2. Distance traveled by the second cyclist: - Speed of the second cyclist = 14 km/h - Time = 3 hours - Distance = Speed × Time = 14 km/h × 3 hours = 42 km

3. Total distance between the villages: - Total distance = Distance traveled by the first cyclist + Distance traveled by the second cyclist - Total distance = 36 km + 42 km = 78 km

Therefore, the distance between the villages when the cyclists meet after 3 hours is 78 km.

Answer

The distance between the two villages when the cyclists meet after 3 hours is 78 km.
