My instructor told me that a C-150 is so stable that if the engine quits at night and all you did was slow down to 60 KIAS, leveled the wings and did nothing else but shut your eyes and pray that you had a 90% chance of survival.
Power lines, water bodies. residences with aviation fuel burn..., your instructor is not retired military.
My FIL and I used to dink around in his Aeronca Champ, and go for the shortest landing rolls we could produce.
He won. Always. He also used to fly a Maule Rocket STOL for the Louisiana Forest service.
Landed on runway 16 into a SW 10-15 kt breeze, hot Louisiana afternoon, serious ground effect. He SAID he got it down to 38 KIAS floating in the ground effect before it kinda plopped onto the runway, … and rolled what we estimated to be less than 30 feet +/-
So I am guessing maybe 20 mph on the runway when he touched down, max.
