latency for Advantage AP & Normal SM

What would be the latency if i have advantage ap & normal sm.

will it be 5 ms or 20 ms…?

I’m running 900 gear in HWS. >15ms to the next hop router

What i meant was a combination of 2450AP & 2400SM

I am running 2.4 and is around 5 to 10 ms on average from a single hop
