Question

Велосипедист и мотоциклист едут навстречу друг другу скорость мотоциклиста 40 км ч а велосипедиста 12 км ч через какое время они встретятся если сейчас между ними 52 км 156 км

Answer 1

Сначала, выясним общую скорость: 40 км/ч + 12 км/ч = 52 км/ч - скорость сближения

Если между ними 52 км, то:

52 км : 52 км/ч = 1 час

Если между ними 156 км, то:

156 км : 52 км/ч = 3 часа

Answer 2

Problem Analysis

We are given the speeds of a cyclist and a motorcyclist who are traveling towards each other. We need to determine the time it takes for them to meet if there is a distance of 52 km between them.

Solution

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

Let's calculate the time it takes for the cyclist and the motorcyclist to meet.

1. The speed of the motorcyclist is given as 40 km/h. 2. The speed of the cyclist is given as 12 km/h. 3. The distance between them is given as 52 km.

Using the formula, we can calculate the time it takes for the motorcyclist and the cyclist to meet:

- Time taken by the motorcyclist: time_motorcyclist = distance / speed_motorcyclist - Time taken by the cyclist: time_cyclist = distance / speed_cyclist

Let's substitute the given values into the formulas and calculate the times.

Calculation

- Time taken by the motorcyclist: time_motorcyclist = 52 km / 40 km/h - Time taken by the cyclist: time_cyclist = 52 km / 12 km/h

Now, let's calculate the values.

Calculation Results

- Time taken by the motorcyclist: time_motorcyclist = 1.3 hours - Time taken by the cyclist: time_cyclist = 4.3 hours

Therefore, the motorcyclist and the cyclist will meet after approximately 1.3 hours.

Answer

The motorcyclist and the cyclist will meet after approximately 1.3 hours.

Note: The calculations were based on the given information and the formulas for time, distance, and speed.
