To find out how long it would take to travel 1,700 miles at a speed of 9 miles per hour, you can use the formula:
\[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]
In this case, the distance is 1,700 miles and the speed is 9 mph.
\[ \text{Time} = \frac{1700 \text{ miles}}{9 \text{ mph}} \approx 188.89 \text{ hours} \]
So, it would take approximately 188.89 hours, or about 7.87 days, to travel 1,700 miles at a speed of 9 mph.
