Question

из одного улья одновременно вылетели в противоположных направлениях две пчелы. через 0.15 часа между ними было 6.3 км найдите скорости полета каждой из пчел если известно что скорость полета одной пчелы в 1.4 раза менье скорости другой

Answer 1

скорость 1 пчелы - х

скорость 2 пчелы - 1,4х

х+1,4х - скорость удаления

0,15*(х+1,4х)=6,3

0,15х+0,21х=6,3

0,36х=6,3

х=17,5 (км/ч) - скорость 1 пчелы

17,5*1,4=24,5 (км/ч) - скорость 2 пчелы

 

Answer 2

скорость полета одной пчелы-x
скорость другой пчелы 1.4x
за  0.15 часа один полетит 0.15x км
другой- (0.15*1.4x) км ,вместе они пролетели 6.3 км
получим уравнение
0.15x+0.15*1.4x=6.3
0.15x+0.21x=6.3
0.36x=6.3
x=17.5

17.5*1.4=24.5
ответ:17.5 км;24.5км;

Answer 3

To find the flight speeds of the two bees, we can set up a system of equations based on the given information. Let's assume the flight speed of one bee is x km/h, and the flight speed of the other bee is 1.4x km/h.

We know that the two bees flew in opposite directions for 0.15 hours and the distance between them was 6.3 km. We can use the formula distance = speed × time to set up the equations.

Equation 1:

The distance covered by the first bee is equal to its speed multiplied by the time: x km/h × 0.15 h = 0.15x km.

Equation 2:

The distance covered by the second bee is equal to its speed multiplied by the time: 1.4x km/h × 0.15 h = 0.21x km.

Since the two bees flew in opposite directions, the sum of their distances should be equal to the total distance between them: 0.15x km + 0.21x km = 6.3 km.

Now, let's solve this equation to find the value of x:

0.15x + 0.21x = 6.3 0.36x = 6.3 x = 6.3 / 0.36 x ≈ 17.5

Therefore, the flight speed of the first bee is approximately
