Question

Из двух сел новременно навстречу друг другу отправились велосипидист и пешеход.пешеход шел со скоростью 3 км/ч что в 4 раза меньше скорости велосипедиста. Найдите расстояние между селами если велосипедист пешеход встретились через 3 часа начала движений найдите расстояние между двумя селами , если велосипедист и пешеход встретились через 3 часа после начала движения

Answer 1

3 на 4 = 12 - скорость велосипедиста
12+3 = 15
15 на 3 = 45 км расстояние между селами

Answer 2

Problem Analysis

We are given that a cyclist and a pedestrian start simultaneously from two villages towards each other. The pedestrian walks at a speed of 3 km/h, which is 4 times slower than the speed of the cyclist. We need to find the distance between the two villages if the cyclist and the pedestrian meet after 3 hours.

Solution

Let's assume the speed of the cyclist is v km/h. Since the pedestrian walks at a speed 4 times slower than the cyclist, the pedestrian's speed is v/4 km/h.

We know that distance = speed × time.

The cyclist and the pedestrian meet after 3 hours, so the distance covered by the cyclist in 3 hours is 3v km, and the distance covered by the pedestrian in 3 hours is 3(v/4) km.

Since they are moving towards each other, the sum of the distances covered by both of them will be equal to the distance between the two villages.

Let's calculate the distance between the two villages using the given information.

Calculation

The distance between the two villages is given by the sum of the distances covered by the cyclist and the pedestrian:

Distance = 3v + 3(v/4)

Simplifying the equation:

Distance = 3v + (3v/4)

Combining like terms:

Distance = (12v + 3v) / 4

Simplifying further:

Distance = 15v / 4

Therefore, the distance between the two villages is 15v / 4 km.

Substituting Values

To find the exact distance between the two villages, we need to know the speed of the cyclist (v). Unfortunately, the given information does not provide the value of v. Without this information, we cannot calculate the exact distance between the two villages.
