Answer:


4\text{ watts}

Explanation:

In physics, the power of a machine is given by
P=(W)/(\Delta t), where
W is work in Joules and
\Delta t is time in seconds.

Convert 2 minutes into seconds:

2 minutes = 120 seconds.

Substitute
W=480 and
\Delta t=120 to solve for
P:


P=(480)/(120)=\boxed{4\text{ watts}}
