Question

cycles for 10 minutes, over a total distance of 400 meters and they pedal against a resistance of 300 N, what is their power

Answer 1

so they pedal against that resistance of 300N

so force is 300N

now he goes to a displacement of 400 m

time would be 10 min and con converting
10×60=600 sec

$\:work \:done \:would \:be$

$force×displacement$

=300×400=120000N

$power=work \:done/Time$

$120000/600=200 \:Watts$
