Question

Из 2 городов, S(расстояние) между которыми составляет = 234 км.Навстречу друг другу выехали велосипедист и мотоциклист.Скорость(V) мотоциклиста=60 км/ч,Скорость(V) велосипедиста=составляет 30% Скорости(V) мотоциклиста. Через сколько они встретятся?

Answer 1

0,3*60=18 км/ч
60+18=78 км/ч
234/78=3 часа

Answer 2

Problem Analysis

We are given that two individuals, a cyclist and a motorcyclist, start from two different cities and travel towards each other. We need to determine how long it will take for them to meet.

Given Information

- Distance between the two cities: 234 km - Speed of the motorcyclist: 60 km/h - Speed of the cyclist: 30% of the motorcyclist's speed

Solution

To find the time it takes for the two individuals to meet, we can use the formula:

Time = Distance / Relative Speed

The relative speed is the sum of the speeds of the motorcyclist and the cyclist.

Let's calculate the relative speed of the cyclist:

Relative Speed = Speed of Motorcyclist + Speed of Cyclist

Given that the speed of the motorcyclist is 60 km/h, we can calculate the speed of the cyclist:

Speed of Cyclist = 30% * Speed of Motorcyclist

Now we can substitute the values into the formula to find the time:

Time = Distance / (Speed of Motorcyclist + Speed of Cyclist)

Let's calculate the time it takes for them to meet.

Calculation

Distance between the two cities: 234 km Speed of the motorcyclist: 60 km/h

Speed of the cyclist: 30% of the motorcyclist's speed

Relative Speed = Speed of Motorcyclist + Speed of Cyclist

Speed of Cyclist = 30% * Speed of Motorcyclist

Time = Distance / (Speed of Motorcyclist + Speed of Cyclist)

Substituting the values:

Speed of Cyclist = 0.3 * 60 km/h = 18 km/h

Relative Speed = 60 km/h + 18 km/h = 78 km/h

Time = 234 km / 78 km/h = 3 hours

Answer

The cyclist and the motorcyclist will meet after approximately 3 hours.
