Frequently Asked Questions
What is the formula for speed, distance, and time?
The fundamental relationship is: Speed = Distance ÷ Time. Rearranging gives Distance = Speed × Time and Time = Distance ÷ Speed. Make sure your units are consistent — if speed is in mph, distance should be in miles and time in hours.
How do I calculate travel time?
Divide the total distance by your average speed. For example, traveling 150 miles at 60 mph takes 150 ÷ 60 = 2.5 hours (2 hours 30 minutes). This assumes constant speed with no stops; add buffer time for traffic, rest breaks, and variable speeds.
How do I convert between mph and km/h?
Multiply mph by 1.60934 to get km/h. For example, 60 mph × 1.60934 ≈ 96.56 km/h. To go the other way, divide km/h by 1.60934 (or multiply by 0.62137). A quick mental shortcut: km/h ≈ mph × 1.6.
