Google maps how to calculate lat long from point A to B?

I have been looking to navigate with google maps from point A to B.

So I have the latitude and longitude of point A %26amp; B and I want to be able to see after 10 minutes where I will be. I take travel time of a plane like 1000km/hour.



I can calculate the distance from point A to B.

But how can I find out the coordinates of latitude and longitude after the 10 minutes.Google maps how to calculate lat long from point A to B?
Slopes will not work. Generally, you will not be changing latitude (or longitude) at a constant rate.



The shortest distance from A to B will be a great circle. You say you figured the distance A to B, and you want the point that is X distance from A, along the line to B. Here is a link to some formulas that will help.



Use the first set of formulas to find the A-B distance and the initial bearing. Then use the second set, using the initial bearing and the A-X distance, to find the point for X. These formulas should be accurate to a kilometer or so.Google maps how to calculate lat long from point A to B?
Speed = distance / time will be your best staring point, and when you work out the distance traveled you can scale it off and get the rough long and lang, however if tour looking for something more precise, you will have to investigate into northerns and easterns
