Question

Из одного скворечника вылетели одновременно в противоположных направлениях два скворца. через 0,15ч между ними было 16,5км. скорость полёта одного 52,4км/ч. найдите скорость второго скворца

Answer 1

52,4*0,15=7,86км пролетел первый скворец
16,5-7,86=8,64км пролетел второй скворец
8,64:0,15=57,6км/ч скорость второго скворца

Answer 2

1) 16,5 : 0,15 = 110 (км . ч ) -скорость удаления 
2) 110-52 ,4 =57 . 6 (км .ч ) -скорость второго скворца
Ответ : 57 . 6 километров . 

Answer 3

Problem Analysis

We are given the following information: - Two sparrows flew out of a birdhouse simultaneously in opposite directions. - After 0.15 hours, the distance between them was 16.5 km. - The speed of one sparrow is 52.4 km/h.

We need to find the speed of the second sparrow.

Solution

Let's assume the speed of the second sparrow is x km/h.

Since the sparrows are flying in opposite directions, the total distance covered by both sparrows in 0.15 hours is equal to the distance between them.

The distance covered by the first sparrow is given by: Distance1 = Speed1 * Time = 52.4 km/h * 0.15 h

The distance covered by the second sparrow is given by: Distance2 = Speed2 * Time = x km/h * 0.15 h

The sum of the distances covered by both sparrows is equal to the distance between them: Distance1 + Distance2 = 16.5 km

Substituting the values, we get: (52.4 km/h * 0.15 h) + (x km/h * 0.15 h) = 16.5 km

Simplifying the equation, we have: 7.86 + 0.15x = 16.5

Now, we can solve for x to find the speed of the second sparrow.

Calculation

Let's solve the equation to find the value of x:

7.86 + 0.15x = 16.5

Subtracting 7.86 from both sides: 0.15x = 8.64

Dividing both sides by 0.15: x = 57.6

Answer

The speed of the second sparrow is 57.6 km/h.
