Yi amfani da wannan dabarar don ƙididdige hanzari. Tunda muna ƙididdige hanzari, ba hanzartawa ba, yi watsi da alamar mara kyau.
Gudun AB = (25 – 20) / (20 – 0) = 5/20 = 1/4 = 0,25 m/s²
Saurin BC = (45 – 25) / (40 – 20) = 20/20 = 1 m/s²
Gudun CD = (35 – 45) / (50 – 40) = 10 / 10 = 1 m/s²
Gudun DE = (25 – 35) / (70 – 50) = 10/20 = 1/2 = 0,5 m/s²
Gudun EF = (0 – 25) / (90 – 70) = 25/20 = 5/4 = 1,25 m/s²
