Odpowiedź:
1. s = v*t = 80 [tex]\frac{km}{h} *0,25 h = 20[/tex] km
2.
a) s = 60 [tex]\frac{km}{h} * 3 h = 180[/tex] km
b) s = 60 [tex]\frac{km}{h} *\frac{1}{3} h = 20[/tex] km
c ) s = 60 [tex]\frac{km}{h} * 4,2 h = 252[/tex] km
Szczegółowe wyjaśnienie:
15 min = [tex]\frac{1}{4}[/tex] h = 0,25 h
20 min = [tex]\frac{1}{3}[/tex] h
1. s= v*t = 80km/h * 1/4h = 20 km
a) s=v*t = 60km/h * 3h = 180 km
b) s=v*t = 60km/h * 1/3h = 20 km
c) s= v*t = 60km/h * 4,2h = 252 h
