Why does the ping go up when using a VPN

When I do a ping speed test it always slows down when using a VPN

Because ping is primarily based on distance, when using a VPN the ping must go from you to the VPN to the destination and back.

When doing a speed test it generally picks a server closest to your location, but when using a VPN it chooses a location closest to the VPN provider.
