The standard highway speed in 100 kph, so a 500 km trip should
take 5 hours.

I like to do math with simple numbers like that.


Stupid example, though. If you're going 100 MPH, a 500 mile
trip also takes five hours. If you're only using one set of
units, it doesn't make any difference what they are.

But.... 100 mph is not a legal speed while 60 mph zones becomes
100 kph zones.

If you can't go 100MPH, you could try figuring half that (50MPH) and
approximating the value for 60MPH. Experience should be helpful in
this case.
