Question

un pieton,miscindu-se uniform rectiliniu,a parcurs un drum de 360m timp de 12min.Determina viteza pietonului,in m/s

Answer 1

v=Δd/Δt
12 min=12*60=720s
d=360m
t=720s
v=360m/720s=1/2=0.5 m/s

Answer 2

$d=360 \ m \\ t=12 \ min=720 \ s \\ \boxed{v-?} \\ \bold{Rezolvare:} \\ \boxed{v= \frac{d}{t} } \\ \Rightarrow v= \frac{360 \ m}{720 \ s} \\ \Rightarrow \boxed{0,5 \ m/s}$
