Question

type the correct answer in each box. use numerals instead of words.
a race car is driven by a professional driver at 99 \\(\frac{\text{miles}}{\text{hour}}\\). what is this speed in \\(\frac{\text{kilometers}}{\text{hour}}\\) and \\(\frac{\text{kilometers}}{\text{minute}}\\)?
1 mile = 1.61 kilometers
1 hour = 60 minutes
round your answers to the nearest tenth.
the speed is equivalent to \\(\square\\) \\(\frac{\text{kilometers}}{\text{hour}}\\), or \\(\square\\) \\(\frac{\text{kilometers}}{\text{minute}}\\).

Explanation:

Step1: Convert miles per hour to kilometers per hour

To convert miles per hour to kilometers per hour, we multiply the speed in miles per hour by the conversion factor (1 mile = 1.61 kilometers). So, we have \( 99 \times 1.61 \).
\( 99\times1.61 = 159.39 \), and rounding to the nearest tenth gives \( 159.4 \) kilometers per hour.

Step2: Convert kilometers per hour to kilometers per minute

Since 1 hour = 60 minutes, we divide the speed in kilometers per hour by 60 to get kilometers per minute. So, we calculate \( \frac{159.4}{60} \).
\( \frac{159.4}{60} \approx 2.7 \) (rounded to the nearest tenth).

Answer:

The speed is equivalent to \( \boldsymbol{159.4} \) \(\frac{\text{kilometers}}{\text{hour}}\), or \( \boldsymbol{2.7} \) \(\frac{\text{kilometers}}{\text{minute}}\).
