--------------------
What speed?
If it's an airplane:
The actual windspeed is 6 m/hr
The actual airspeed is 40 mi/hr
The actual groundspeed is 46 mi/hr
=============
If it's a car:
The actual windspeed is 6 m/hr
The actual airspeed is 34 mi/hr

A: if a small airplane is traveling with a tailwind of 6 mph and the airspeed indicator shows 40 miles per hour, what is the speed of the airplane relative to the ground?
---
the airplane moves with the airmass, and the airmass moves over the ground:
---
40 + 6 = 46
---
answer:
the speed of the airplane relative to the ground = 46 mph
---
B: if a car is traveling with a tailwind of 6 mph and the speedometer shows 40 miles per hour, what is the speed of the car relative to the ground?
---
the car doesn't move with the airmass so its indicated speed is the same as its speed relative to the ground.
---
answer:
the speed of the car relative to the ground = 40 mph
