unreal values resulted from distance_to

[Suhad Faisal]

Hello 

I try to simulate trajectory of agent for several days and several hours, but when I compute the distance between two points and dividing the distance on the time to obtain the speed of an agent, the resulted value of distance_to is not real (very big values). I checked my data they are correct but the operator gives unreal data.   so I attached my model and its own files 

thanks in advance to help and advice me 

cheers
