Мотоциклист проехал 180км. какое расстояние может проехать за это же время велосипедист, если его
скорость в 4 раза меньше? какова скорость мотоциклиста, если скорость велосипедиста 15 км в час?

Ответы на вопрос




180/4= 45 км
скорость мотоциклиста 15*4=60 км в час



Question Analysis
The question asks for a detailed explanation of a scenario involving a motorcyclist and a cyclist. The motorcyclist travels a distance of 180 km, and the question asks for the distance the cyclist can travel in the same amount of time if their speed is four times slower. Additionally, the question asks for the speed of the motorcyclist if the cyclist's speed is 15 km/h.
Answer
To find the distance the cyclist can travel in the same amount of time, we need to determine the ratio of their speeds. The cyclist's speed is four times slower than the motorcyclist's speed. Let's assume the motorcyclist's speed is x km/h. Therefore, the cyclist's speed is x/4 km/h.
Now, we can use the formula distance = speed × time to calculate the distance the cyclist can travel. Since the time is the same for both the motorcyclist and the cyclist, we can set up the following equation:
180 km = (x/4) km/h × time
To find the value of time, we need to know the speed of the motorcyclist or the cyclist. The question provides the speed of the cyclist, which is 15 km/h. We can substitute this value into the equation:
180 km = (15/4) km/h × time
To find the value of time, we can rearrange the equation:
time = (180 km) / ((15/4) km/h)
Now, let's calculate the value of time:
``` time = (180 km) / ((15/4) km/h) ```
Using the given values, we can calculate the value of time.
Calculation
``` time = (180 km) / ((15/4) km/h) = (180 km) × (4/15) h/km = 48 h ```
Therefore, the value of time is 48 hours.
Now, we can calculate the distance the cyclist can travel in 48 hours using their speed of 15 km/h:
``` distance = speed × time = 15 km/h × 48 h = 720 km ```
Therefore, the cyclist can travel a distance of 720 km in the same amount of time that the motorcyclist traveled 180 km.
To find the speed of the motorcyclist, we can use the formula distance = speed × time with the given values:
``` 180 km = speed × 48 h ```
Solving for speed:
``` speed = 180 km / 48 h = 3.75 km/h ```
Therefore, the speed of the motorcyclist is 3.75 km/h.
Summary
In summary, the distance the cyclist can travel in the same amount of time that the motorcyclist traveled 180 km is 720 km. The speed of the motorcyclist is 3.75 km/h.
