Question

Задача С одного цветка одновременно слетели и полетели в противоположные стороны две бабочки. Через 4 с расстояние между ними было 18 м. Скорость полета одной бабочкой равна 2,4 м/с. Какова скорость полета другой бабочи

Answer 1

Известную скорость умножить на пройденное время и вычесть из общего расстояния,а остаток разделить на 4.
2,4х4=9,2 ;
18-9,2=8,8 ;
8,8:4=2,2 - искомое.

Answer 2

Problem Analysis

We have two butterflies that simultaneously flew in opposite directions from a flower. The distance between them after 4 seconds was 18 meters. We know the speed of one butterfly is 2.4 m/s. We need to find the speed of the other butterfly.

Solution

To solve this problem, we can use the formula: speed = distance / time.

Let's assume the speed of the second butterfly is x m/s.

The distance covered by the first butterfly in 4 seconds is: 2.4 m/s * 4 s = 9.6 meters.

The distance covered by the second butterfly in 4 seconds is: x m/s * 4 s = 4x meters.

The total distance between the butterflies after 4 seconds is 18 meters. Therefore, we can write the equation:

9.6 meters + 4x meters = 18 meters

Simplifying the equation:

4x meters = 18 meters - 9.6 meters

4x meters = 8.4 meters

Dividing both sides of the equation by 4:

x meters = 8.4 meters / 4

x meters = 2.1 meters per second

Therefore, the speed of the second butterfly is 2.1 m/s.

Answer

The speed of the second butterfly is 2.1 m/s.
