1. V= 60km/h, t= 2.5h, s= V*t= 150km
2. V= 450km/h, t= 20min= ⅓h, s= V*t= 450km/h*⅓h= 150km
3. s= 15km, t= 0.5h, V= s/t= 15km/0.5h= 30km/h
4. s= 240km, t= 45min= ¾h, V= s/t= 240km/¾h= 320km
5. V= 40km/h, s= 180km, t= s/V= 180km / 40km/h= 4.5h
6. V= 240km/h, s= 4km, t= s/V= 4km / 240km/h= 1/60h= 1min
