For the car to move around a circle at a constant speed there must be a centripetal force. In this problem, the friction force is equal to the centripetal force.
Fc = m * v^2 ÷ r
Ff = μ * m *g
m * v^2 ÷ r = μ * m *g
v =√( r * μ * g)
2 * π * r = 271.4
r = 135.7/π
The radius of the circle is approximately 43 meters.
v =√(135.7/π * 0.5 * 9.8)
v = √664.63/π
The maximum speed is approximately 14.5 m/s. I hope this is helpful for you.

∑F = ma
Nμ = m v² / r
mg μ = m v² / r
g μ = v² / r
v = √(g μ r)
Find radius from circumference then plug in and solve.
