how much is 1.47 m/s

I don't know Aziz

that is 1.47*60*60 = 5292m/hour = 5.292km/hour

I think the people of California must walk faster than the ones in Sydney.  

1.47 m/s is about the average rate people walk.

Eh, Melody....that rate is about 3.2 mi/hr......i.e., about the rate of a "medium" pace......definitely not "slow," but definitely not "fast," either.......Aziz's observation seems reasonable.......

Yes, it is reasonable so long as I don't have to keep up for any length of time.  I am a dawdler.
