3)12*3=36км путь пешехода и велос.за 3 часа
4)36+8=44км от деревни до поселка
Problem Analysis
We are given that a pedestrian is walking from a village to a settlement at a speed of 4 km/h. After 2 hours, a cyclist leaves the settlement and meets the pedestrian after 3 hours. We need to find the distance between the village and the settlement.Solution
Let's assume the distance between the village and the settlement is d km.The pedestrian's speed is 4 km/h, so in 2 hours, the pedestrian covers a distance of 8 km.
The cyclist's speed is twice that of the pedestrian, so the cyclist's speed is 8 km/h. In 3 hours, the cyclist covers a distance of 24 km.
Since the cyclist meets the pedestrian after 3 hours, the total distance covered by both the pedestrian and the cyclist is equal to the distance between the village and the settlement.
Therefore, we can set up the equation:
8 km + 24 km = d km
Simplifying the equation:
32 km = d km
So, the distance between the village and the settlement is 32 km.
Answer
The distance between the village and the settlement is 32 km.
