What did Leona mean when she observed your can't measure the distance between my block and city hale in miles?

Leona's observation suggests that the relationship between her neighborhood (referred to as "my block") and the city's center (City Hall) cannot be quantified solely by physical distance. Instead, it implies that there are deeper social, cultural, or emotional factors that define the connection between the two places. This could reflect disparities in resources, experiences, or community identity that aren't captured by mere mileage. Essentially, she highlights that some distances are more complex than they appear on a map.
