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.
