Question

Из двух сёл находящихся на расстоянии 14 км друг от друга выехали одновременно в противоположных направлениях удаляясь друг от друга велосипедист и мотоциклист. Велосипедист ехал со скоростью 13 км\ч а мотоциклист со скоростью 32 км\ч. На каком расстоянии друг отдруга будут велосипедист и мотоциклист через 4 часа после выхода.

Answer 1

1) 13+32=45 (км/ч) скорость удаления;
2)  45*4=180 (км) окажутся велосипедисты друг от друга через 4 часа без расстояния между поселками;
3)  180+14=204 (км) полное расстояние между ними через 4 часа.
           Ответ: 204 км.

Answer 2

Problem Analysis

We are given two villages that are 14 km apart. A cyclist and a motorcyclist start simultaneously from these villages and move away from each other in opposite directions. The cyclist travels at a speed of 13 km/h, while the motorcyclist travels at a speed of 32 km/h. We need to determine the distance between the cyclist and the motorcyclist after 4 hours.

Solution

To find the distance between the cyclist and the motorcyclist after 4 hours, we need to calculate the total distance traveled by each of them.

The cyclist travels at a speed of 13 km/h for 4 hours, so the distance traveled by the cyclist is: Distance_cyclist = Speed_cyclist * Time = 13 km/h * 4 h = 52 km.

Similarly, the motorcyclist travels at a speed of 32 km/h for 4 hours, so the distance traveled by the motorcyclist is: Distance_motorcyclist = Speed_motorcyclist * Time = 32 km/h * 4 h = 128 km.

Since they are moving in opposite directions, the total distance between them is the sum of the distances traveled by each of them: Total_distance = Distance_cyclist + Distance_motorcyclist = 52 km + 128 km = 180 km.

Therefore, after 4 hours, the cyclist and the motorcyclist will be 180 km apart from each other.

Answer

After 4 hours, the cyclist and the motorcyclist will be 180 km apart from each other.
