Question

efetue as transformações de unidade a)5 m/s= km/h b)8 m/s= km/h c)10 m/s= km/h d)72 km/h= m/s e)108 km/h= m/s f)144 km/h= m/s g)1 h= min h)1 h= s i)5 km = m

Answer 1

a) 5x3,6= 18 km/h
b)8x3,6 = 28,8 km/h
c)10x3,6= 36 km/h
d)72/3,6= 20 m/s
e)108/3,6= 30 m/s
f)144/3,6= 40 m/s
g 1h= 60 min 
h) 1h = 1 min = 60s 60minx60s= 3600s
i) 1 km = 1000 metros / logo 5 km = 5000 metros
