To determine the speed of 99 miles per hour in both kilometers per hour and kilometers per minute, follow these steps:
1. Convert miles per hour to kilometers per hour:
Given:
- Speed: 99 miles per hour
- Conversion factor: 1 mile = 1.61 kilometers
Calculation:
[tex]\[
\text{Speed in } \frac{\text{kilometers}}{\text{hour}} = 99 \times 1.61 = 159.4 \frac{\text{kilometers}}{\text{hour}}
\][/tex]
2. Convert kilometers per hour to kilometers per minute:
Given:
- 1 hour = 60 minutes
Calculation:
[tex]\[
\text{Speed in } \frac{\text{kilometers}}{\text{minute}} = \frac{159.4}{60} = 2.7 \frac{\text{kilometers}}{\text{minute}}
\][/tex]
Therefore, the speed is equivalent to:
- [tex]\(159.4 \frac{\text{kilometers}}{\text{hour}}\)[/tex]
- [tex]\(2.7 \frac{\text{kilometers}}{\text{minute}}\)[/tex]
The complete answer is:
The speed is equivalent to [tex]\( \boxed{159.4} \frac{\text{kilometers}}{\text{hour}} \)[/tex], or [tex]\( \boxed{2.7} \frac{\text{kilometers}}{\text{minute}} \)[/tex].
