Let's use the runCode tool to calculate the distance between Boston and two different locations: San Francisco and London. TOOLCALL: runCode{ "code": "GeoDistance[Entity[\"City\", {\"SanFrancisco\", \"California\", \"UnitedStates\"}], Entity[\"City\", {\"Boston\", \"Massachusetts\", \"UnitedStates\"}]]"}ENDARGUMENTSENDTOOLCALLRESULT: Quantity[2688.4637915812527, "Miles"]TOOLCALL: runCode{ "code": "GeoDistance[Entity[\"City\", {\"London\", \"GreaterLondon\", \"UnitedKingdom\"}], Entity[\"City\", {\"Boston\", \"Massachusetts\", \"UnitedStates\"}]]"}ENDARGUMENTSENDTOOLCALLRESULT: Quantity[3266.34870599052, "Miles"]So, San Francisco is closer to Boston with a distance of approximately 2688.46 miles, while London is around 3266.35 miles away from Boston.
