And while you're at it, you should use your time machine to ensure that pi is defined as the ratio of a circle's circumference to its radius, not its diameter.

Work is the integral of force over distance, not time. (In the case of constant force, W=F*D.) Because of the treadmill, A is applying force over a larger distance, so to do work at the same rate as B, the force must be correspondingly less.
