The maximum speed that a driver can travel on a banked track without relying on friction to make the turn is given by the formula:

v = √(rgtanθ)

where v is the speed of the car, r is the radius of the turn, g is the acceleration due to gravity, and θ is the angle of the bank.

Substituting the given values, we get:

v = √(9.8 m/s^2 x 301 m x tan11°) 
v ≈ 42 m/s

Therefore, the best choice is C) 42 m/s as this is the maximum speed that a driver can travel on the Daytona Speedway without relying on friction to make the turn.
