Question

Из двух городов одновременно навстречу друг другу выехали два велосипедиста. 'через 3 часа расстояние между ними было равно 186 км. рдин из низ езал чо скоростью 12 км/ ч. а другой со скоростью 15 км / ч. найди расстояние между ними.

Answer 1

12 + 15 = 27 км/час скорость их сближения
3 * 27 = 81 км за три часа они приблизились друг к другу на 81 км
186 + 81 = 267 км  было расстояние между ними изначально

Answer 2

Problem Analysis

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

Solution

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

Distance = Speed × Time

Let's calculate the distance traveled by each cyclist after 3 hours:

Cyclist 1: - Speed: 12 km/h - Time: 3 hours - Distance = 12 km/h × 3 hours = 36 km

Cyclist 2: - Speed: 15 km/h - Time: 3 hours - Distance = 15 km/h × 3 hours = 45 km

Now, let's find the total distance between the two cyclists by adding up the distances traveled by each cyclist:

Total distance = Distance traveled by Cyclist 1 + Distance traveled by Cyclist 2 = 36 km + 45 km = 81 km

Therefore, the distance between the two cyclists after 3 hours is 81 km.

Answer

The distance between the two cyclists after 3 hours is 81 km.
