Question

Из двух поселков одновременно навстречу друг другу выехали два мотоциклиста и встретились через 3 часа. первый мотоциклист ехал со скоростью 23 км/ч а второй со скоростью 18 км\ч найдите расстояние между поселками Варианты 1)123 2)148 3)167 4)294

Answer 1

23+18=41 км/ч скорость сближения
41×3=123 км-расстояние между поселками

Answer 2

Problem Analysis

We have two motorcyclists who start simultaneously from two different villages and meet each other after 3 hours. The first motorcyclist travels at a speed of 23 km/h, while the second motorcyclist travels at a speed of 18 km/h. We need to find the distance between the villages.

Solution

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

Distance = Speed × Time

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

Calculation

The first motorcyclist travels at a speed of 23 km/h for 3 hours, so the distance traveled by the first motorcyclist is:

Distance1 = Speed1 × Time = 23 km/h × 3 hours = 69 km.

Similarly, the second motorcyclist travels at a speed of 18 km/h for 3 hours, so the distance traveled by the second motorcyclist is:

Distance2 = Speed2 × Time = 18 km/h × 3 hours = 54 km.

To find the total distance between the villages, we add the distances traveled by each motorcyclist:

Total Distance = Distance1 + Distance2 = 69 km + 54 km = 123 km.

Therefore, the correct option is 1) 123 km.

Answer

The distance between the two villages is 123 km (Option 1)
