Question

Велосипидист и мотоциклист выехали одновременно из одного пункта по одной и той же дороге в одном направлении скорость мотоциклиста равна 40 км час а велосипедиста 12 км час через сколько часов между ними будет 56 км

Answer 1

40-12=28км/ч разница в скоростях
56÷28=2 ч через это время

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 on a road. The speed of the motorcyclist is 40 km/h, and the speed of the cyclist is 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 it takes *t* hours for the distance between the cyclist and the motorcyclist to be 56 km.

The distance traveled by the motorcyclist in *t* hours is given by: distance_motorcyclist = speed_motorcyclist × t.

Similarly, the distance traveled by the cyclist in *t* hours is given by: distance_cyclist = speed_cyclist × t.

According to the problem statement, the distance between the cyclist and the motorcyclist is 56 km. Therefore, we can write the equation: distance_motorcyclist - distance_cyclist = 56.

Substituting the values, we get: (speed_motorcyclist × t) - (speed_cyclist × t) = 56.

Simplifying the equation, we have: (40 × t) - (12 × t) = 56.

Solving for *t*, we get: 28 × t = 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.
