distance (s)=100m
time
T₁=10
T₂=10.2
T₃=10.4
T₄=10.6
by v=[latex] \frac{s}{t} [/latex]
we get
V₁=[latex] \frac{100}{10}[/latex]
V₁=10m/s

V₂=[latex] \frac{100}{10.2} [/latex]
V₂=9.8m/s

V₃=[latex] \frac{100}{10.4} [/latex]
V₃=9.61 m/s

V₄=[latex] \frac{100}{10.6} [/latex]
V₄=9.43 m/s

V₁:V₂:V₃:V₄ = 10 : 9.8 : 9.61 : 9.43
