I stand corrected:

T (seconds) = R*C

In that time the voltage of the capacitor,
will drop to ~ 37% of the initial charge voltage. 

If the capacitor is at 2.3 V and the motor draws 0.2 A (about 11 Ohms),
the T is 11 * 2.7 or about 30 seconds to 0.85 V.

Your calculation of 11 seconds run time appears to be good.  :)
