Step 1:I'll solve this problem step by step using the specified LaTeX formatting guidelines:
Step 2:: Calculate Driving Time at 55 Miles per Hour
\text{Time} = \frac{2000 \text{ miles}}{55 \text{ miles per hour}} = 36.36 \text{ hours}
To find the driving time, we'll use the distance-rate-time formula: Substituting the values:
Step 3:: Calculate Driving Time at 70 Miles per Hour
\text{Time} = \frac{2000 \text{ miles}}{70 \text{ miles per hour}} = 28.57 \text{ hours}
Using the same formula:
Final Answer
- Driving time at 55 miles per hour: 36.36 \text{ hours} - Driving time at 70 miles per hour: 28.57 \text{ hours} Note: The difference in driving time is about 7.79 hours due to the increased speed.
