Szczegółowe wyjaśnienie:
1) V = 20km/h T = 0,5 h = 1/2 S= V*T
S= 20km/h * 0,5h = 10km
2) V= 60km/h T= 45min = 3/4h S= V*T
S= 60km/h * 3/4h = 45km
3) V= 320km/h T= 36min- 3/5h S= V*T
S= 320km/h * 3/5h = 192km
4) V= 480km/h T= 6min- 1/10h S= V*T
S= 480km/h * 1/10h = 48km
5) V= 5km T= 4,5h S= V*T
S= 5km * 4,5h = 22,5
6) S= 16km T= 30min- 1/2h V= S: T
V= 16km : 1/2h= 16km * 2/1 = 32km/h
7) S= 14km T= 10min- 1/6h V= S:T
V= 14km : 1/6h = 14km * 6/1 = 84km/h
8) S= 1cm T= 5s- 1/12min V= S: T
V= 1cm : 1/12min = 1cm * 12/1 = 12cm/min
9) S= 1,9km T= 3min- 1/20h V= S: T
V= 1,9km : 1/20h = 1,9 * 20/1 = 38km/h
10) S= 80m T= 15s V= S:T
V= 80m : 15s = 5,3(3)m/s= 19,2 km/h
11) S= 60km V= 15km/h T= S:V
T= 60km : 15km/h = 4h
12) S= 25m V= 5m/min T= S:V
T= 25m : 5m/min = 5min
13) S= 87cm V= 3cm/s T= S:V
T= 87cm : 3cm/s = 29s
14) S= 6km V= 20km/h T= S:V
T= 6km : 20km/h = 0,3h = 18min
15) S= 210km - 210 000m V=250m/s T= S:V
T= 210 000m : 250m/s = 840s : 60 = 14min.
16) S= 40 km V= 120km/h T= S:V
T= 40km : 120km/h = 40/1 * 1/120 = 1/3h = 20 min
T= S:V17) 30m/s - km/h ? 30m/s * 3600/1000 = 108km/h
18) 144km/h - m/s ? 144km * 3600/1000 = 40m/s
mam nadzieje że pomogłam i wszystko jest dobrze
