3 hours
4 hours
30 hours
40 hours

Answer 1

To estimate the number of hours Jerrod’s family drove, you can use the formula:

\[
\text{Time} = \frac{\text{Distance}}{\text{Speed}}
\]

In this case, the distance is 1,778 miles, and the average speed is 61.7 miles per hour.

Calculating the exact time:

\[
\text{Time} = \frac{1778 \text{ miles}}{61.7 \text{ miles per hour}} \approx 28.8 \text{ hours}
\]

Now, looking at the options provided:

- 3 hours
- 4 hours
- 30 hours
- 40 hours

The best estimate of the number of hours the family drove is **30 hours**.
