This pdf is like 10yrs old, but graph in the top right outlines the rate based on distance.

The first line is around 267 Mbps, so it looks like they're expecting 10 Mbps at max distance to Mars.

That's still a really good speed, but I think the bigger question might be latency.

Latency would be determined almost completely by the speed of light itself.

Earth to Mars ranges from 5.5*10^10 to 4.0*10^11 m, and light travels 3*10^8 m/s.

Earth-Mars latency is therefore from 3 to 22 minutes one-way.
