Uh, it depends on the size of the game and the speed of your internet connection/hotspot

For me it takes 51 seconds or 7 minutes. Depending on the size and connection.

SERVERS! 
google has faster servers thats why games tend to DL faster there. However GooglePlay does NOT allow for resume DL... if you drop connection while DLn from GP you lose all the progress on that DL and have to start from 0 again this is because GP DLs the game into a cloud server and then unpacks and installs the game on the device once its completed the DL.
Here on APKpure what you DL goes straight to the device this allows for resuming after a disconnect.

For me it started out rlly fast but it's a little slow these days ✌
