Question

Скорость велосипеда 12 км\ч. Это в 3 раза больше скорости пешехода, но в 6 раз меньше скорости автобуса. Найди скорость пешехода и автобуса

Answer 1

1. 4 - пешеход
12 на 6 равно 72 - автобус

Answer 2

12+3=15
15-6=9
По моему так

Answer 3

Calculation of Pedestrian and Bus Speeds

To find the speed of the pedestrian and the bus, we can use the information given in the question.

The speed of the bicycle is given as 12 km/h, which is 3 times faster than the speed of the pedestrian and 6 times slower than the speed of the bus.

Let's denote the speed of the pedestrian as v_p and the speed of the bus as v_b.

From the given information, we can set up the following equations:

1. The speed of the bicycle is 3 times faster than the speed of the pedestrian: ``` 12 km/h = 3 * v_p ```

2. The speed of the bicycle is 6 times slower than the speed of the bus: ``` 12 km/h = v_b / 6 ```

To find the speed of the pedestrian and the bus, we can solve these equations simultaneously.

Solving the Equations

Let's solve the equations to find the values of v_p and v_b.

From equation 1, we can solve for v_p: ``` v_p = 12 km/h / 3 = 4 km/h ```

From equation 2, we can solve for v_b: ``` v_b = 12 km/h * 6 = 72 km/h ```

Therefore, the speed of the pedestrian is 4 km/h and the speed of the bus is 72 km/h.

Conclusion

Based on the given information, the speed of the pedestrian is 4 km/h and the speed of the bus is 72 km/h.
