What speed would a fly with mass of 0.55 need in order to have the same kinetic energy as the auto mobile of 7.610`4

It depends on variables you did not specify.   As you probably know the relationship between mass, velocity and kinetic inergy is KE = mv2/2.     Since you didn't give either the mass or the velocity of the auto the problem is underdetermined.  The missing units are equally important.
