MapKit JS wrong calculation distance and travel time of route

Recently I've implement MapKit JS in my project and start testing it.
Map, routing, overlays and points work fine. So, in my old implementation I have function which calculate distance and time travel between two points using Google Maps. I started implementing this with MapKit JS route function https://developer.apple.com/documentation/mapkitjs/mapkit/directions/2973874-route which return callback, using this callback you can get distance (in meters) and travel time (in seconds). When I decide to convert meters to miles and seconds to mins I noticed that there is some difference to Apple Maps, Google Map, etc, in short it calculates wrong. I tried a lot of waypoints and compare to Apple Maps and Google Maps, there is difference. I understand that I can't ask a solution but I don't know how to explain my customers about difference in 0.5 - 0.7 miles in every order?
