Given:
Distance traveled, d = 398 miles
Average speed, v = 49 miles per hour.
Let's find the time it took you to drive.
To find the time, apply the formula:
[tex]time=\frac{distance}{speed}[/tex]Thus, we have:
[tex]\begin{gathered} time=\frac{398\text{ miles}}{49\text{ mph}} \\ \\ time=8.12\text{ hours}\approx8\text{ hours} \end{gathered}[/tex]Therefore, the estimated time it took to drive is 8 hours.
ANSWER:
8 hours.
