To determine how much time it would take Bo to travel 1152 miles, we first need to find his driving rate in miles per hour.
Bo drove 448 miles in 7 hours, so his driving rate is calculated as follows:
\[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} = \frac{448 \text{ miles}}{7 \text{ hours}} = 64 \text{ miles per hour} \]
Now, we'll use this driving rate to find out how long it would take him to travel 1152 miles. We use the formula for time:
\[ \text{Time} = \frac{\text{Distance}}{\text{Rate}} \]
Substituting in the known values:
\[ \text{Time} = \frac{1152 \text{ miles}}{64 \text{ miles per hour}} = 18 \text{ hours} \]
Thus, it would take Bo 18 hours to travel 1152 miles at the same rate.
