Question

Из сусидных селищ двое тубильцив попливли назутрич один одному .перший тубилець плив зи швидкистю12км/год а другий 15 км/год.яка видстань миж селищами якщо вони зустрилися через 4 години.

Answer 1

1. 12+15=27 км/час -общая скорость (скорость сближения)
2. 27*4=108 км расстояние между поселками

Answer 2

Calculating the Distance Between Two Villages

To calculate the distance between the two villages, we can use the formula:

distance = speed × time

Let's calculate the distance based on the given speeds and time.

The first villager's speed is 12 km/h, and the second villager's speed is 15 km/h. They meet after 4 hours.

Calculating the Distance Traveled by Each Villager

The distance traveled by the first villager can be calculated as: distance1 = speed1 × time

Substituting the values: distance1 = 12 km/h × 4 h = 48 km

Similarly, the distance traveled by the second villager can be calculated as: distance2 = speed2 × time

Substituting the values: distance2 = 15 km/h × 4 h = 60 km

Finding the Distance Between the Villages

When the two villagers meet, the sum of the distances traveled by each of them will be equal to the total distance between the villages.

So, the total distance between the villages is: total distance = distance1 + distance2

Substituting the calculated values: total distance = 48 km + 60 km = 108 km

Therefore, the distance between the two villages when they meet after 4 hours is 108 kilometers.
