1.
v = 50 km/h
t = 2,5 h
s = v·t = 50km/h · 2,5h = 125 km
2.
v = 450 km/h
t = 30 min = 0,5 h
s = v · t = 450km/h · 0,5h = 225 km
3.
s = 15 km
t = 0,5 h
v = s/t = 15km / 0,5h = 30 km/h
4.
s = 150 km
t = 45 min = 3/4 h = 0,75 h
v = s/t = 150km / 0,75h = 200 km/h
5.
v = 120 km/h
s = 80 km
t = s/t = 80km / 120km/h = 0,(6) h ≈ 0,67 h
6.
v = 25 km/h
s = 5 km
t = s/v = 5km / 25km/h = 0,2 h
