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

I agree with Pierre, also you are rounding the results. If the points are not far enough apart, you're rounding may just provide 0. I don't see how the rounding tolerance is defined. I always calculate in meters - it makes things much easier. I'd suggest following the SI standard units in your code. Your output also shows that the timeDelta is zero, so no distance was actually calculated.
