Question

Выразите в м/с 10 км/мин,15 м/мин,72 км/ч,54 км/мин,20 м/мин.

Answer 1

Объяснение:

1 ч = 60 мин = 3600 с

1) 10 км/мин = 10000/60 = 166,(6) м/с

2) 15 м/мин = 15/60 = 0,25 м/с

3) 72 км/ч = 72000/3600 = 20 м/с

4) 54 км/ч = 54000/3600 = 15 м/с

5) 20 м/мин = 20/60 = 1/3 м/с = 0,3(3) м/с

Answer 2

Conversion of Units

To convert the given values from kilometers per minute (km/min) and meters per minute (m/min) to meters per second (m/s) and kilometers per hour (km/h), we can use the following conversion factors:

1 km/min = 1000 m/min = 1000/60 m/s = 16.67 m/s1 km/h = 1000/3600 m/s = 0.2778 m/s Now let's convert each value:

1. 10 km/min: - To m/s: 10 km/min * (1000 m/min / 60) = 166.67 m/s - To km/h: 10 km/min * (60 min/h) = 600 km/h

2. 15 m/min: - To m/s: 15 m/min * (1/60) = 0.25 m/s - To km/h: 15 m/min * (1/60) * (60 min/h) = 0.25 km/h

3. 72 km/h: - To m/s: 72 km/h * (1000/3600) = 20 m/s - To km/min: 72 km/h * (60 min/h) = 4320 km/min

4. 54 km/min: - To m/s: 54 km/min * (1000 m/min / 60) = 900 m/s - To km/h: 54 km/min * (60 min/h) = 3240 km/h

5. 20 m/min: - To m/s: 20 m/min * (1/60) = 0.33 m/s - To km/h: 20 m/min * (1/60) * (60 min/h) = 0.33 km/h

Therefore, the conversions are as follows:

- 10 km/min = 166.67 m/s, 600 km/h - 15 m/min = 0.25 m/s, 0.25 km/h - 72 km/h = 20 m/s, 4320 km/min - 54 km/min = 900 m/s, 3240 km/h - 20 m/min = 0.33 m/s, 0.33 km/h
