[question] trips.json schema and 1000 stepSize attribute

[kuanb]

I can see in the src how each trip in trips.json is assembled:

trip-simulator/src/agent.js

Lines 183 to 184 in a1497e6

	trip_duration: this.path.duration / 1000,
	trip_distance: this.path.distance * 1000,

Where does the 1000 constant in the denominator come from? I think it's related to the stepSize from the simulation being hardcoded to 1000:

trip-simulator/src/simulation.js

Line 18 in a1497e6

this.stepSize = 1000;

If so, are the trip_duration and trip_distance values the in seconds and meters, respectively?

I ask because I'd assume the time would converted /60 (min) /360 (hrs), so wondering where the 1000 is coming from.

Same question roughly with distance value.

[kuanb]

this.path = await this.simulation.route(this.location, destination);

OSRM returns a duration float, in seconds. You factor rate * time and then factor by 1000 to get distance in meters since rate in kmph.

So that would be total distance covered, right? And, if so, then why re-divide by 1000 only to compute duration for completed trip?

I feel like I am missing just one step in the logic as I am reading through it 🤔
