Frequently Asked Questions
What is the formula for driving time?
Time = Distance / Speed. For example, 240 miles at an average speed of 60 mph requires 4.0 hours of driving time.
Why include a traffic buffer?
Freeway driving rarely sustains ideal speed due to traffic congestion, toll booths, and rest breaks. A 15-25% buffer gives a realistic real-world ETA.
