Question

из двух поселков выехали одновременно навстречу друг другу выехали два велосипедиста и встретились через 3 часа скорость первого 12км ч какой скоростьюехал второй велосипедист если расстояние между посёлками 60кмч

Answer 1

1) 12 * 3 = 36 км - проехал первый велосипедист

2) 60 - 36 = 24 км - проехал второй велосипедист

3) 24 : 3 = 8 км/час - скорость второго велосипедиста

Answer 2

Problem Analysis

Two cyclists start simultaneously from two different villages and meet each other after 3 hours. The speed of the first cyclist is given as 12 km/h, and the distance between the villages is 60 km. We need to find the speed of the second cyclist.

Solution

Let's assume the speed of the second cyclist is x km/h.

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

The distance covered by the first cyclist in 3 hours is: 12 km/h * 3 hours = 36 km.

The distance covered by the second cyclist in 3 hours is: x km/h * 3 hours = 3x km.

Since the total distance between the villages is 60 km, we can write the equation: 36 km + 3x km = 60 km.

Simplifying the equation, we have: 3x km = 60 km - 36 km.

Simplifying further, we get: 3x km = 24 km.

Dividing both sides of the equation by 3, we find: x km = 24 km / 3.

Therefore, the speed of the second cyclist is 8 km/h.

Answer

The speed of the second cyclist is 8 km/h.
