Question

Одновременно из двух сел, расстояние между которыми равно 24 км ,отправились в путь навстречу друг другу велосипедист и пешеход.через 1,5 ч они встретились.какова скорость каждого, если скорость велоситедиста больше скорости пешехода в 3 раза?

Answer 1

1)24:1,5=16(км/ч)скорость движения
велосипедист-3х
пешеход-х
х+3х=16
4х=16
х=4
2)4*3=12(км/ч)скорость велосипедиста
Ответ:4км/ч;12км/ч
увы,по-другому не решить

Answer 2

Problem Analysis

We have two individuals, a cyclist and a pedestrian, who start simultaneously from two different villages and meet after 1.5 hours. The distance between the villages is 24 km. We need to determine the speed of each person given that the cyclist's speed is three times greater 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 greater, the cyclist's speed is 3x km/h.

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

The time taken by both the cyclist and the pedestrian to meet is 1.5 hours.

Let's calculate the speed of each person.

Calculation

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

The distance between the villages is 24 km, and the time taken to meet is 1.5 hours.

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

For the pedestrian: x = distance / time = 24 km / 1.5 hours = 16 km/h.

For the cyclist: 3x = 3 * 16 km/h = 48 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.
