÷ by 1000 . to change from km to m

Answer 2

133.33 meters per minute.

Explanation:

We are asked to convert 8 kilometers per hour to meters per minute.

We know that one kilometer equals 1000 meters and 1 hour equals 60 minutes.

`\text{8 kilometers per hour}=\frac{\text{8 km}}{\text{hour}}* \frac{\text{1000 meter}}{\text{Km}}*\frac{\text{1 hour}}{\text{60 min}}`

`\text{8 kilometers per hour}=\frac{8* \text{1000 meters}}{\text{60 min}}`

`\text{8 kilometers per hour}=\frac{8000 \text{ meters}}{\text{60 min}}`

`\text{8 kilometers per hour}=\frac{133.33\text{ meters}}{\text{ min}}`

Therefore, our required speed would be 133.33 meters per minute.
