Zad. 1.
t = 16 h 10 min - 14 h 40 min 1 h 30 min = 1,5 h
s = 38 km + 53 km = 91 km
v = ?
v = s/t
v = 91 km / 1,5 h = 60 2/3 km/h ≈ 61 km/h
Zad. 2. (s_A = )
s_A = 200 m
t_A = 20 s
v_A = 200 m / 20 s = 10 m/s
s_B = 300 m
t_B = 15 s
v_B = 300 m / 15 s = 20 m/s
Zad. 3.
Prędkość ciała rosła na odcinkach 1, 3 i 7.
