Answer:
1.931 kilometres is the answer of 1.2 miles
<u>Explanation</u>:
Resistivity of silver wire =
Resistivity of copper wire = 
Resistance = Resistivity *length/cross sectional area

So,

For E calculation
For copper
E = resistivity * current density
E = Resistivity * current/area

For silver

Potential difference 
For silver
Potential difference = 
For copper
Potential difference =
