a)
Dane:
V = 18km/h
t = 30min =0,5h
Szukane:
s = ?
Obliczenia:
[tex]s = 18 \times 0.5 = 9km[/tex]
b)
Dane:
V = 18km/h
t = 65min = 65/60h
Szukane:
s = ?
Obliczenia:
[tex]s = 18 \times \frac{65}{60} = \frac{1170}{60} = 19.5km[/tex]
c)
Dane:
V = 18km/h
t = 2h 55min = 2 i 55/50h
Szukane:
s = ?
Obliczenia:
[tex]s = 18 \times 2 \frac{55}{60} = 18 \times \frac{175}{60} = \frac{3150}{60} = 52.5km[/tex]
