To calculate the distance that Jeremiah flew, you can use the formula:
\[ \text{Distance} = \text{Speed} \times \text{Time} \]
In this case, the speed is 304.6 miles per hour and the time is 2.7 hours.
Now, substitute the values into the formula:
\[ \text{Distance} = 304.6 , \text{miles/hour} \times 2.7 , \text{hours} \]
Calculating that gives:
\[ \text{Distance} = 304.6 \times 2.7 = 822.42 , \text{miles} \]
So, the correct answer is 822.42 miles.
