• use the multiplication (×) key on the keyboard to enter your answer in scientific notation, not the letter x.

provide your answer below:

miles per minute

Explanation:

Step1: Recall conversion factor

1 hour = 60 minutes.

Step2: Set up conversion

Speed in miles per minute = $\frac{6.706\times 10^{8}\text{ miles}}{1\text{ hour}}\times\frac{1\text{ hour}}{60\text{ minutes}}$.

Step3: Calculate

$\frac{6.706\times 10^{8}}{60}= 0.1117666\cdots\times 10^{8}=1.117666\cdots\times 10^{7}$.

Step4: Round to four - significant figures

$1.118\times 10^{7}$.

Answer:

$1.118\times 10^{7}$
