Final answer:
Mara drives at a rate of 45 miles per hour. By multiplying this rate by 8 hours, it is calculated that Mara will drive 360 miles in 8 hours.
Step-by-step explanation:
Mara drives 225 miles in 5 hours. To determine how far she will drive in 8 hours at this same rate, we need to calculate her driving speed and then use that to find the total distance.
Step-by-Step Calculation
- Determine Mara's speed by dividing the distance by the time. Speed = Distance/Time = 225 miles / 5 hours = 45 miles per hour.
- Once we have her speed, we multiply it by the desired time to find the distance. Distance in 8 hours = Speed x Time = 45 miles/hour x 8 hours.
- Therefore, Mara will drive 360 miles in 8 hours at this rate.
