Penny Lane drove 250 miles in 4 hours. At the rate, how many miles will she travel in 8 hours? What is Penny’s rate of speed?

Solution:
1. Given:
- Distance traveled: 250 miles
- Time taken: 4 hours

2. Calculate Penny's rate of speed:
\text{Speed} = \frac{\text{Distance}}{\text{Time}} = \frac{250 \text{ miles}}{4 \text{ hours}} = 62.5 \text{ miles per hour}

3. Calculate the distance Penny will travel in 8 hours at this rate:
\text{Distance} = \text{Speed} \times \text{Time} = 62.5 \text{ miles per hour} \times 8 \text{ hours} = 500 \text{ miles}
