Learning how to run faster is done by running faster (even if that sounds like stating the obvious).
Not necessarily – I used to do 10km in c.39m, but smashed my knee up a few years back and went to ultra instead. Did a 12km XC in 48m a few weeks back – that’s on no speed training in years. It’s still not Hobo fast, but faster than I thought possible without training ‘fast’.
Other people have told me they increased short distance speed only doing long-distance running, this is the first time I've seen it.
