I use Google Maps mainly to get a idea of traffic in front of us while traveling. What ever the mileage is says to the destination I just divide by 50 and disregard their estimate arrival time.

Though I use a Garmin dash mount GPS, I do use Google maps when planning my route. (Note: I don't have a smartphone hence the Garmin). I actively look for gas stops that are easy in/out, other stops, etc. To answer your question, if Google says 5 hours (your example) on an A to B route (meaning: no big stops other than maybe gas), I will add 1 to 1.5 hours of time.
Keep in mind Google figures time based on speedlimits and other factors, and it does not consider RV speeds...so yes, i do add time.

X2!! arrival time using this method has always been within 15 mins on 300-400 mile trips.

I still use my Microsoft Streets and Trips 2011 version to plan. Then I compare it what Google Maps says. I often need to add a destination to Google.
MS S&T lets me set my speed at the slowest and also lets me add in rest breaks.

I'm also a "50 mph" person. That number includes gas stops but not meal stops. After many years of experience, we have determined that 50 is a real-world number -- a 400 mile trip really takes 8 hours.

50ish mph average, not matter what the mapping software or GPS says.
Over 7 years full-timing, 46 states, that's about right.

I'm also a 50MPH average kind of guy. Almost always works well to give a fairly accurate eta.
Google maps eta drives me nuts. Even though I know they are way off, it still drives me nuts that they say I'm going to get there at such-and-such a time. At times when I've not been towing I've experimented to see if it is even possible to meet their eta expectations by driving the speed limit. Couldn't do it. I suspect that their eta is calculated by using data from other drivers, whom we all know mostly exceed the speed limit all the time. I don't think you can meet google maps eta without speeding.

We use x-ways only when necessary so go thru small towns. We figure an average of 45 miles per hour and that figure also allows for a brief breaks to walk around a bit ( 10 min) and a half hour lunch period. Many US highways are divided 4 lane with a lot less traffic, so that's our choice when possible.

Love Google maps, been using it for navigation for at least 5-6 years now. I still have a couple Garmins still on the shelf collecting dust. I like the live traffic, suggested detours when there is construction or accidents etc. Time seems accurate when driving solo but I also figure 50mph towing as well.
