Q1. In a 100m track event, the time taken by four runners is 10 sec., 10.2 sec., 10.4 sec and 10.6 sec. Find the ratio of their speed.

Sagot :

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

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

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

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

V₁:V₂:V₃:V₄ = 10 : 9.8 : 9.61 : 9.43
