Our robot geared the atwood and drill motor (in low) together to give an output shaft speed of 300 rpm. We then used a 2:1 chain drive to provide 150 rpm at the wheels which were 9" in diameter.

Speed in inches/minute can be calculated by multiplying the circumference of the wheel by the rpm. Further calculations would translate it into something meaningful like feet/second.

The gearbox and this info is available in the white papers. Look for Dual Motor and Team 716. Other gearbox papers give the same type of information. Do not be afraid to do a little investigation (and calculation) on your own. The stuff you learn in FIRST is the real world application of the stuff you learn in school.
