A curve of radius 69 m is banked for a design speed of 95 km/h.

If the coefficient of static friction is 0.40 (wet pavement), at what range of speeds can a car safely make the curve? [Hint: Consider the direction of the friction force when the car goes too slow or too fast.]

Express your answers using two significant figures separated by a comma.
