Question

Przelicz na jednostki i zapisz obliczenia 42km/h= m/s 5m/s= km/h 24m/s= dm/min 54km/h= m/s 10m/s= km/h 14dm/min= m/s 48km/h= m/s 20m/s= dm/min Plix na dzisiaj

Answer 1

42 km/h = (42*1000/3600)m/s = 11.67 m/s

5 m/s = (5/1000*3600)km/h = 18 km/h

24 m/s = (24*10*60)dm/min = 14400 dm/min

54 km/h = (54*1000/3600)m/s = 15 m/s

10 m/s = (10/1000*3600)km/h = 36 km/h

14 dm/min = (14/10/60)m/s = 0.023 m/s

48 km/h = (48*1000/3600)m/s = 13.33 m/s

20 m/s = (20*10*60)dm/min = 12000 dm/min

 

Answer 2

a)

42km/h=42m/s / 3,6 ≈ 11,7m/s

b)

5m/s=5km/h·3,6=18km/h

c)

24m/s=24dm/min·10·60=14400dm/min

d)

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

e)

10m/s=10km/h·3,6=36km/h

f)

14dm/min=14m/s·0,1/60≈0,0233m/s

g)

48km/h=48m/s / 3,6 ≈ 13,33m/s

h)

20m/s=20dm/min·10·60=12000dm/min
