[tex]\tt{\huge{\blue{Explanation:}}}[/tex]

The power of an object doing a work W in a given time t is given by

[tex]\boxed{P = \frac{W}{t}}[/tex]

where:

P = power

W = work

t = time

[tex]\tt{\huge{\red{Solution:}}}[/tex]

Solving for P

Note: 3 min = 180 s

[tex]P = \dfrac{W}{t}[/tex]

[tex]P = \dfrac{\text{27,000 J}}{\text{180 s}}[/tex]

[tex]\boxed{P = \text{150 W}}[/tex]

Therefore, the power output of the cyclist is 150 W.
