Why does 5 mph slower feel like it adds a bunch of time but 5 mph faster doesn’t affect the eta much.

Something that’s always bothered me about driving is I can drive 5 mph over and barely speed up the gps, however if I accidentally drive 5 under the speed limit, (My brand new truck doesn’t have a speeding) it will add a bunch of extra time. Is there an equation or something that shows you how fast you’d have to go to actually lower the time needed to arrive. Is it just a mental thing or is it math. Any and all information welcome!

Let’s say you’re driving 100 miles if you drive at 105 mph you’ll arrive in 57 min

If you drive 95 mph it will be 63 min

That’s a 10% slower result.

Maybe that helps. Not sure if it does. In my life I’d rather just take it easy and get there 6 min slower.
