Question

Одновременно из двух сел,расстояние между которыми 24км. отправились в путь навстречу друг другу велосипедист и пешеход. через 1.5 ч. они встретились. определите скорость каждого из них, если известно, что скорость велосипедиста больше скорости пешехода в 3 раза.

Answer 1

V=S:T
V=24:1.5
V=1.6
1.6+3=4.6
Ответ:V=4.6

Answer 2

Problem Analysis

We have two individuals, a cyclist and a pedestrian, who start simultaneously from two different villages towards each other. The distance between the villages is 24 km. After 1.5 hours, they meet each other. We need to determine the speed of each individual given that the cyclist's speed is three times faster than the pedestrian's speed.

Solution

Let's assume the speed of the pedestrian is x km/h. Since the cyclist's speed is three times faster, the cyclist's speed is 3x km/h.

To find the speed of each individual, we can use the formula: speed = distance / time.

The time it takes for both individuals to meet is 1.5 hours. Since they are moving towards each other, the total distance covered by both individuals is equal to the distance between the villages, which is 24 km.

Let's calculate the speed of each individual.

Calculation

The speed of the pedestrian is x km/h, and the speed of the cyclist is 3x km/h.

The time taken by both individuals to meet is 1.5 hours.

Using the formula speed = distance / time, we can calculate the speed of each individual.

For the pedestrian: - Speed = Distance / Time - Speed = 24 km / 1.5 hours - Speed = 16 km/h

For the cyclist: - Speed = Distance / Time - Speed = 24 km / 1.5 hours - Speed = 16 km/h

Therefore, the speed of the pedestrian is 16 km/h, and the speed of the cyclist is 48 km/h.

Answer

The speed of the pedestrian is 16 km/h, and the speed of the cyclist is 48 km/h.
