Question

v=72kilometri pe oră
Timpul=4 secunde
Distanța=???

Answer 1

$v=72 \ km/h=20 \ m/s \\ t=4 \ s \\ \boxed{d-?} \\ \bold{Rezolvare:} \\ \boxed{v= \frac{d}{t}} \\ \Rightarrow d=v \cdot t \\ d=20 \ m/s \cdot 4 \s \\ \Rightarrow \boxed{d=80 \ m}$

Answer 2

V=72 KM/h=20m/s
t=4 s
rezolvare:
d=v*t
d=20m/s*4s
d=80m
