Čas 4h 15 min = 255 min – [4*60+15]
1h 12 min 6 s = 4326 s – [3600+720+6]
48 min = 0,8 h – [48÷60]
16 min 24s = 16,4 min – [16+(24÷60)=16,4]
7200 s = 2 h – [7200÷3600=2]
Rychlost
120 km/h = 33,33 m/s – [120 000÷3600=33,33]
20 m/s = 72 km/h
Selskej rozum
- 20 m………….1s
- 0,02 km……....1s
- 0,02*3600=72
Koeficient 3,6
- 20*3,6=72 km/h
70km/h = 1,16 km/min – [70÷60]
14 m/min = 140 dm/min – [14*10]
50 km/h = 833,3 m/min – [50 000÷60]
7200 s = 2 h – [7200÷3600=2]
