Question

Длина окружности колеса велосипеда 1.4/5м.За 1 секунду колесо совершает 1.2/3 оборота.Какое S проедет велосипед за 5 минут

Answer 1

5 мин=300 сек
1) 1 4/5*1 2/3=9/5*5/3=3 м - проедет за 1 сек
2) 300*3=900 м - проедет за 5 мин

Answer 2

Calculating Distance Traveled by the Bicycle

To calculate the distance traveled by the bicycle, we can use the formula:

Distance = Circumference of the wheel × Number of revolutions

Given: - Circumference of the wheel = 1.4/5 m - Number of revolutions in 1 second = 1.2/3

Let's calculate the distance traveled by the bicycle in 1 second using the given values.

Calculating Distance Traveled in 1 Second

Using the given values: - Circumference of the wheel = 1.4/5 m - Number of revolutions in 1 second = 1.2/3

We can calculate the distance traveled in 1 second using the formula: Distance = Circumference of the wheel × Number of revolutions

Substituting the given values: Distance = (1.4/5) m × (1.2/3) revolutions

Calculating the result: Distance = (1.4/5) m × (1.2/3) = 0.933333... m

So, the distance traveled by the bicycle in 1 second is approximately 0.9333 meters.

Calculating Distance Traveled in 5 Minutes

To calculate the distance traveled by the bicycle in 5 minutes, we need to convert 5 minutes to seconds and then multiply the distance traveled in 1 second by the total number of seconds in 5 minutes.

1 minute = 60 seconds So, 5 minutes = 5 × 60 = 300 seconds

Now, we can calculate the distance traveled in 5 minutes using the distance traveled in 1 second: Total Distance = Distance in 1 second × Total seconds in 5 minutes

Substituting the values: Total Distance = 0.9333 m × 300 seconds = 280 meters

Therefore, the bicycle will travel approximately 280 meters in 5 minutes.
