Get a bicycle. :)
Seriously, it depends a lot on state of tune of the
engine/gearbox/tyres/road conditions etc. IME (not with a SGV) the most
economical speed is only found empirically, but so much depends upon what
you're doing, how the car is and so many other factors no-one could say,
correctly.
eg, go 50mph with a 10 mph tail wind and you'd probably get better mpg than
30 mph with a 10mph head wind ...

On a flat surface with no particularly adverse variables, 55mph in top gear
is usually tuned to give optimum economy.

unless your car is a moped and does 35mph, this theory may be different.

By definition, a car is not a moped.
