Question

Va rog !
1.
v= 35 km pe ora
delta t =35 min
d(distanta)=?
2.
v=600 m pe sec
delta t=0,005 s
d=?
3.
delta t=1,5 h
v= 3,5 m pe sec
d=?
4.
v=40 m pe s
delta t=20 min
d=?

Answer 1

1.
v=35km/h; Δt=35min=35/60h
d=v×Δt=35×35/60≈20,4km
2.
v=600m/s
Δt=0,005s
d=v×Δt=3m
3.
v=3,5m/s
Δt=1,5h=90min=5400s
d=v×Δt=18900m=18,9km
4.
v=40m/s
Δt=20min=1200s
d=v×Δt=48000m=48km
