x=distancia.
t=tiempo.

Datos:
x=480 m
t=2 min.(60 s/1min)=120 s
v=x/t
v=480 m/120 s=4 m/s
Sol:B) 4 m/s.
20)
Datos:
v=25 m/s
t=4 min. (60 s/1 min)=240 s
v=x/t ⇒x=v.t
x=25 m/s.240 s=6000 m.(1Km / 1000 m)=6 Km
Sol:C) 6 Km.
21)
v=90 Km/h.(1000 m/1Km).(1h/3600 s)=25 m/s.
x=200 m
v=x/t ⇒t=x/v
t=200 m / 25 m/s= 8 s.
Sol:C) 8 s.
