Question

Их двух городов одновременно навстречу друг другу выехали два велосипедиста. Через 3 часа расстояние между ними было равно 186 км. Один из них ехали со скоростью 12км/ч а другой 15км/ч . Найди расстояние между гродами. ( ποmoгυτе)

Answer 1

1) 12 + 15 =  27(км/ч) - скорость сближения.
2) 27 * 3 = 81(км) - проехали за 3 часа.
3) 186 + 81 = 267(км) - всего.
Ответ: 267 км.

Answer 2

Problem Analysis

Two cyclists start simultaneously from two different cities and travel towards each other. After 3 hours, the distance between them is 186 km. One cyclist is traveling at a speed of 12 km/h, while the other is traveling at a speed of 15 km/h. We need to find the distance between the two cities.

Solution

Let's assume the distance between the two cities is x km.

The first cyclist is traveling at a speed of 12 km/h, so in 3 hours, they would have covered a distance of 12 km/h * 3 h = 36 km.

The second cyclist is traveling at a speed of 15 km/h, so in 3 hours, they would have covered a distance of 15 km/h * 3 h = 45 km.

The total distance covered by both cyclists in 3 hours is 36 km + 45 km = 81 km.

Since the distance between the two cyclists after 3 hours is 186 km, we can set up the following equation:

x = 81 km + 186 km

Simplifying the equation:

x = 267 km

Therefore, the distance between the two cities is 267 km.

Answer

The distance between the two cities is 267 km.
