4) 18km/h=

Zadanie 2.

Zamień podane m/s na km/h:

1) 30m/s=

2) 15m/s=

3) 5m/s=

4) 70m/s=

Answer 1

Odpowiedź:

Wyjaśnienie:

1 km/h=1*1000 m/3600 s=10/36 m/s

15 km/h=15*10/36 m/s=4,1(6) m/s

60 km/h= 60*10/36  m/s=50/3 m/s=16,(6) m/s

10 km/h=10*10/36 m/s=100/36=2,(7) m/s

18 km/h=18*10/36 m/s=20 m/s

_____________________

1 m/s=1*1/1000 km:1/3600 s=1/100-*3600=3,6 km/h

30 m/s=30*3,6 km/h=108 km/h

15 m/s=15*3,6 km/h=54 km/h

5 m/s=5*3,6 km/h=18 km/h

70 m/s=70*3,6 km/h=252 km/h
