Answer 1

40-12=28км/ч скорость отдаления мотоциклиста
56:28=2ч -время через которое расстояние между ними будет 56км

Answer 2

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously from the same point and travel in the same direction. The speed of the motorcyclist is 40 km/h, and the speed of the cyclist is 12 km/h. We need to find out how many hours it will take for the distance between them to be 56 km.

Solution

Let's assume that it takes 't' hours for the distance between the cyclist and the motorcyclist to be 56 km.

The distance covered by the motorcyclist in 't' hours can be calculated using the formula: distance = speed * time. Therefore, the distance covered by the motorcyclist is 40t km.

Similarly, the distance covered by the cyclist in 't' hours is 12t km.

The difference in distance between the motorcyclist and the cyclist is given as 56 km. Therefore, we can set up the following equation:

40t - 12t = 56

Simplifying the equation, we get:

28t = 56

Dividing both sides of the equation by 28, we find:

t = 2

Therefore, it will take 2 hours for the distance between the cyclist and the motorcyclist to be 56 km.

Answer

It will take 2 hours for the distance between the cyclist and the motorcyclist to be 56 km.
