The power of the kitchen blender is #250 J/s#

Explanation:

Let's use the following formula:

#P = W/T#

  • P stands for power and it is measured in Watts (W) or (J/s)
  • W stands for work and it is measured in Joules (J)
  • T stands for time and it is measured in seconds (s)

We know the work that was done as well as the time, both of which have the correct units. All we do now is plug in the given values for W and T and solve for P like this:

#P = (3750 J)/(15 s)#

#P = 250 J/s#
