Question

Велосипедист и мотоциклист выехали одновременно из одного пункта в одном направлении. Скорость мотоциклиста 40км/ч ,а велосипедисто 12км/ч через сколько часов расстояние между ними будет 56км

Answer 1

1) 40 -12= 28 км/ч  - скорость удаления

2) 56 : 28=2 часа - искомое время

Answer 2

1)40 км\ч-12км\ч=28км\ч(скорость удаления друг от друга)

56\28=2часа

вроде все ))))

Answer 3

Problem Analysis

We are given that a cyclist and a motorcyclist start simultaneously 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 how many hours it will take for the distance between them to be 56 km.

Solution

To solve this problem, we can use the formula: distance = speed × time.

Let's assume that the time taken by both the cyclist and the motorcyclist is 't' hours.

The distance traveled by the motorcyclist in 't' hours is given by: distance_motorcyclist = speed_motorcyclist × t.

The distance traveled by the cyclist in 't' hours is given by: distance_cyclist = speed_cyclist × t.

According to the problem, the distance between them is 56 km. Therefore, we have the equation: distance_motorcyclist - distance_cyclist = 56.

Substituting the values, we get: (40 × t) - (12 × t) = 56.

Simplifying the equation, we have: 28 × t = 56.

Dividing both sides of the equation by 28, we get: 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.
