Average speed

Formula
Average speed = distance ÷ time. Metres per second = km/h ÷ 3.6. Pace for each kilometre = 60 ÷ speed for km/h, measured in minutes per kilometre.
Example wey show the calculation
100 km for 2 hours: average speed = 100 ÷ 2 = 50 km/h. For metres per second, na 50 ÷ 3.6 = 13.89 m/s. Pace = 60 ÷ 50 = 1.20 minutes per kilometre; dat na 1 minute 12 seconds per kilometre.
Where e fit work and limits
Dis na average speed for di whole trip; e no tell you how fast you go for any one moment. Stops, traffic and hills all dey inside di average. E no dey consider direction: dis na speed, wey be scalar, no be velocity as vector, even though people dey mix di names for everyday talk. Time must pass zero; zero time no give meaningful speed.
Questions wey people dey ask often
Average speed or speed for one instant?
Na average: total distance over total time. Your speedometer dey show instantaneous speed, wey fit higher or lower for any moment. Trip wey get stops fit get high speedometer reading but low average.
Why divide by 3.6 for m/s?
Because 1 km/h = 1,000 metres for 3,600 seconds, and 1,000 ÷ 3,600 = 1 ÷ 3.6. So 50 km/h ÷ 3.6 = 13.89 m/s.
Wetin be pace, and why minutes per kilometre?
Pace na inverse of speed: time for each unit of distance. Runners and walkers dey use am because to maintain "6 minutes per kilometre" dey easier than "10 km/h".
I fit enter miles and minutes?
No be directly for here. Convert first (1 mile = 1.60934 km, minutes ÷ 60 = hours). Di speed converter for dis site fit convert di result afterwards.
Round trip dey change anything?
No, if you enter total distance and total time. Mind dis trap: to go at 60 km/h and return at 40 km/h no dey give average of 50 km/h. Di slower part dey take longer, so di true average for equal distances na 48 km/h.
Wetin if time na zero?
Division by zero no get answer, so di page dey ask for time above zero instead of showing infinity.
