Question

Из двух городов одновременно навстречу друг другу выехали 2 велосипедиста. через 3 часа расстояние между ними было равно 186 км. один из них ехал со скоростью 12 км в час а другой со скоростью 15 км в час. найди расстояние между городами

Answer 1

12*3=36 км - проехал 1 вел-т
15*3=45 км - проехал 2 вел-т
186+36+45=267 км- расстояние между городами

Answer 2

Problem Analysis

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

Solution

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

The first cyclist is traveling at a speed of 12 km/h. So, in 3 hours, the distance traveled by the first cyclist is 12 km/h * 3 h = 36 km.

The second cyclist is traveling at a speed of 15 km/h. So, in 3 hours, the distance traveled by the second cyclist is 15 km/h * 3 h = 45 km.

Now, let's calculate the remaining distance between the two cyclists after 3 hours.

The remaining distance between the two cyclists is the initial distance between them minus the distance traveled by each cyclist.

Initial distance between the two cyclists = 186 km

Distance traveled by the first cyclist = 36 km

Distance traveled by the second cyclist = 45 km

Remaining distance = 186 km - 36 km - 45 km = 105 km

Therefore, the distance between the two cities is 105 km.

Answer

The distance between the two cities is 105 km.
