a)150m/s = ...............km/s

b)15m/min=...............m/s

c)150km/min=.............m-s

d)15km/h=.................m/s

e)150km/s=................m/s

f)15m/s=...................m/min

g)159m/s=..................km/min

h)15m/s=...................km/h

Answer 1

a)150m/s = 150* 1/1000 km/s = 150/1000 km/s = 0,15 km/s

b)15m/min=15* m/60s = 0,25 m/s

c)150km/min=150* 1000m/60s = 150000m/60s = 2500 m/s

d)15km/h=15 * 1000m/3600s = 15000m/3600s =150/36 m/s = 50/12 m/s = 4 2/12 m/s = 4 1/6 m/s

e)150km/s= 150 * 1000m/s = 150000 m/s

f)15m/s= 15 m/1/60min = 15*60/1 m/min = 900 m/min

g)159m/s= 159 * 1/1000 km/ 1/60min = 159/1000 * 60/1 km/min = 9,54 km/min

h)15m/s= 15* 1/1000km/1/3600h = 15/1000 * 3600 km/h = 54 km/h

Answer 2

a) 0,15km/s

b) 0,25 m/s

c) 2500 m/s

d) 4,1(6) m/s

e) 150000 m/s

f) 900 m/min

g) 9,54 km/min

h) 54 km/h
