Question

Велосипедист и мотоциклист выехали одновременно из одного пункта в одном направлении.Скорость мотоциклиста 40 км/ч,а велосипедист 12км/ч.Какова скорость их удаления друг от друга?Через сколько часов расстояние между ними будет 56 км?

Answer 1

Тут в ответах такая задача уже есть

Answer 2

1.12+40=52км. 2.2×525=104км.

Answer 3

Problem Analysis

We have a cyclist and a motorcyclist who start from the same point and travel in the same direction. The motorcyclist has a speed of 40 km/h, while the cyclist has a speed of 12 km/h. We need to determine the rate at which they are moving away from each other and how long it will take for the distance between them to reach 56 km.

Solution

To find the rate at which they are moving away from each other, we can subtract the speed of the cyclist from the speed of the motorcyclist:

Relative speed = Motorcyclist's speed - Cyclist's speed

Substituting the given values:

Relative speed = 40 km/h - 12 km/h = 28 km/h

Therefore, the rate at which they are moving away from each other is 28 km/h.

To find the time it takes for the distance between them to reach 56 km, we can divide the distance by the relative speed:

Time = Distance / Relative speed

Substituting the given values:

Time = 56 km / 28 km/h = 2 hours

Therefore, it will take 2 hours for the distance between them to reach 56 km.

Conclusion

The rate at which the cyclist and motorcyclist are moving away from each other is 28 km/h. It will take 2 hours for the distance between them to reach 56 km.
