I'm not sure I understand this. Do you mean:
a) What speed should the wheels turn to move the robot at;
b) What speed should the modules for the wheels rotate at (to translate);
or c) what should the output speed for the motors be?
If it's b), which is the impression I get, that's way too fast. 60 RPM = 1 rev/sec. That's going to be uncontrollable, or close to it. You tell it to turn, and by the time you tell it to stop turning, you've done a 180-degree turn.
If it's a) or c), you're too slow by a long shot. With a), 60 RPM would get you (assuming 6" wheels):
6" * Pi = circumference "
Circumference " * 60 RPM = x" / minute
x" / minute / 60 sec/min = y"/second
y"/second / 12 = z fps
If I did my math right, that's about 1.5 fps. That's not fast enough.
Now, if it's motor output, then you need a faster motor, or one that can take being geared up. Otherwise, you'll be even slower than the above calculations indicate.
