Question

Oblicz:

a) v= 3 km/h s= 6 km t= ?

b) s= 12 cm v= 4 km/h t=?

c) t= 5h v= 30km/h s=?

d) t= 10h s= 30 km v= ?

e) s= 40 m v= 40 km/h t= ?

Answer 1

a)v= s/t  t=s/v  t= 6 km/3km/h=2h  t=2h

b) 12cm=0,00012km  t=0,00012km/4km/h=0,00003h  t=0,00003h

c) v=s/t   s=vt   s= 30km/h * 5h=150km  s=150km

d) v=s/t  v=30km/10h=3km/h   v=3km/h

e) 40m= 0,04km t=s/v  t= 0,04km/40km/h=0,001h   t=0,001h
