The time from mars to Earth is 3-20 minutes depending on orbit.
Perseverance to MRO is 2 mbits/sec but only when it's overhead of the rover. MRO to Earth is 0.5 - 4 mbits per second.
While it takes around 10 seconds to transmit an image at 2mbit/s, the whole system has several store and forward steps adding significantly more delay. And a bunch of starlink-like satellites in medium orbit would for sure help to bridge the gap.
