Question

Скорость машины 60км ч, скорость велосипедиста в 5 раз меньше. Велосипедист проехал расстояние от своего села до железнодорожной станции за 2 часа за сколько минут можно это расстояние можно проехать на машине

Answer 1

60:5=12км\ч-скорость велос-та

12*2=24км-расстояние до станции
24:60=0,4ч=15мин-можно проехать на машине

Answer 2

Calculating Travel Time for the Cyclist and the Car

To calculate the time it takes for the cyclist to travel from the village to the railway station and compare it with the time it takes for a car to cover the same distance, we can use the given information about the speeds of the cyclist and the car.

Given: - Speed of the car = 60 km/h - Speed of the cyclist = 5 times less than the speed of the car

Calculating the Cyclist's Speed

The speed of the cyclist can be calculated by dividing the speed of the car by 5.

Speed of the cyclist = 60 km/h / 5 = 12 km/h

Calculating the Distance Traveled

The distance traveled by the cyclist can be calculated using the formula: \[ \text{Distance} = \text{Speed} \times \text{Time} \]

Time Taken by the Cyclist

Given that the cyclist took 2 hours to travel from the village to the railway station, we can calculate the distance using the cyclist's speed.

\[ \text{Distance} = \text{Speed} \times \text{Time} \] \[ \text{Distance} = 12 \text{ km/h} \times 2 \text{ h} = 24 \text{ km} \]

Time Taken by the Car

To find out how many minutes it would take for the car to cover the same distance, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

\[ \text{Time} = \frac{24 \text{ km}}{60 \text{ km/h}} = 0.4 \text{ hours} \]

Converting 0.4 hours to minutes: \[ 0.4 \text{ hours} \times 60 \text{ minutes/hour} = 24 \text{ minutes} \]

Therefore, the car can cover the distance from the village to the railway station in 24 minutes.
