a)

`V=10m/s=10*(1/(1000)km)/(1/(3600)h)=(10)/(1000)*(3600)/1(km)/h=(3600)/(100)(km)/h=36(km)/h `

b)

`V=16m/s=16*(1/(1000)km)/(1/(3600)h)=(16)/(1000)*(3600)/1(km)/h=(3600*16)/(1000)(km)/h=57,6(km)/h `

c)

`V=50(cm)/s=50*(1/(100000)km)/(1/(3600)s)=(50)/(100000)*(3600)/1(km)/h=(50*3600)/(100000)(km)/h=1,8(km)/h `

d)

`V=13(mm)/s=13*(1/(1000000)km)/(1/(3600)h)=(13)/(1000000)*(3600)/1(km)/h=(13*3600)/(1000000)(km)/h=0,0468(km)/h`
