Answer 1

Ответ:

Пошаговое объяснение:

6 км = 1 час

Нам нужно кол — во метров за 30 мин.

1 час = 60 мин

6 км = 60 мин

30 мин это половина 60 мин. (60 : 2 =30) соответственно и 6 км нужно разделить на 2.

6 : 2 =3 км.

3 км = 3000 м

Бауржан пройдёт 3000 м за 30 мин

Answer 2

Problem a)

To find out how many meters Bauryzhan will travel in 30 minutes, we need to convert the given speed from kilometers per hour to meters per minute.

Given: - Speed of Bauryzhan: 6 km/h - Time: 30 minutes

To convert kilometers per hour to meters per minute, we can use the following conversion factors: - 1 kilometer = 1000 meters - 1 hour = 60 minutes

Let's calculate the distance Bauryzhan will travel:

1. Convert the speed from kilometers per hour to meters per minute: - Speed in meters per minute = (Speed in kilometers per hour) * (Conversion factor: 1000 meters / 1 kilometer) / (Conversion factor: 60 minutes / 1 hour)

Substituting the given values: - Speed in meters per minute = (6 km/h) * (1000 meters / 1 kilometer) / (60 minutes / 1 hour)

Simplifying the expression: - Speed in meters per minute = (6 * 1000) meters / (60) minutes

Calculating the value: - Speed in meters per minute = 100 meters / minute

2. Calculate the distance Bauryzhan will travel: - Distance = (Speed in meters per minute) * (Time in minutes)

Substituting the given values: - Distance = (100 meters / minute) * (30 minutes)

Calculating the value: - Distance = 3000 meters

Bauryzhan will travel 3000 meters in 30 minutes.
