NiMH battery pack's ability to provide stable voltage and current

I have a battery pack consisting of 2100 mAH, AA 1.2 V NiMH batteries connected in series (7.2 V in total). I have calculated that my system would draw a total of 1.1 A in the worst-case max current draw scenario, with most of the current drawn by motors being driven intermittently. I have a voltage regulator circuit using the LM2940-5.0 chip, with bulk and decoupling capacitors connected in all power and motor driver circuits of the system. Knowing this information alone, do you think the battery can provide a stable voltage and current for the components to continue operation and for the microcontroller to stay within operating voltage for 20 to 30 minutes?

It sounds fine except I wouldn't power motors from the 5V supply: connect them to the 7.2V rail and just use 5V for the logic circuits.

That's exactly what I'm doing (I omitted attaching the schematics to avoid overloading my question). Would that be fine from your experience?

Please post the schematic.

You should always post a schematic if you can. I you want to cut down, then cut the text not the schematic.

I have attached my motor driver and voltage regulator circuit for my logic circuits.
