Question

Из двух гнезд одновременно навстречу друг другу вылетели 2 аиста. Скорость одного 40 км/ ч, скорост другого 41 км/ч. Через сколько часов они встретятся, если расстряния между гнездами 162 км?

Answer 1

Через 2 часа они встретятся

Answer 2

Problem Analysis

Two storks are flying towards each other from two nests. The first stork's speed is 40 km/h, and the second stork's speed is 41 km/h. The distance between the nests is 162 km. We need to find out how many hours it will take for them to meet.

Solution

To solve this problem, we can use the concept of relative speed. When two objects are moving towards each other, their relative speed is the sum of their individual speeds. We can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Relative Speed}} \]

Calculation

The relative speed of the two storks is \( 40 \, \text{km/h} + 41 \, \text{km/h} = 81 \, \text{km/h} \). Plugging this into the formula, we get: \[ \text{Time} = \frac{162 \, \text{km}}{81 \, \text{km/h}} = 2 \, \text{hours} \]

Answer: The storks will meet in 2 hours.
