how fast does he drive

got a good one after quite some days

A man always drives at the same speed at all times. He makes it from A direct to C in 30 minutes; from A through B to C in 35 minutes; and from A through D to C in 40 minutes. Distance from point B to C is 10 miles, same distance from C to D. By the way angle C is right angled. Points A, B, C and D are 4 corners of a quadrilateral and labeled in a counterclockwise manner. How fast does he drive?
