Frequently Asked Questions
Distance between two points?
Straight line: d = sqrt((x2-x1)^2 + (y2-y1)^2). Geographic: Haversine formula for Earth curvature.
Driving distance?
Follows roads, not straight lines. Use mapping tools. Typically 10-40% longer than straight-line.
What is Haversine formula?
Calculates great-circle distance between two points on a sphere from latitude and longitude.
Miles to kilometers?
Multiply miles by 1.609. Divide km by 1.609 for miles.
Distance, speed, time relation?
D = S x T. At 60 mph for 2.5 hours = 150 miles.
