Calculating Speed for a navigation app without getSpeed() method

Question

I am developing an app which is more of a time-shift racing between your friends.

I need to calculate speed of a moving vehicle, and I don\'t want to use Locat

Answer 1

Omg.....

Location

Check this method - it allows you to calculate distance between 2 geo points, just divide it by your time. It should be much more accurate than yours as it calculates distances with much better approximation (WGS83 instead of using sin, cos and rest of this stuff).

Good, general idea is to keep all your data in plain units like m, s, kg etc. and make changes only for showing data to user.
