Given: Energy input = 100 W

Energy output = 1000 W

Formula: Efficiency = Energy Output/Energy Input x 100 %

Efficiency = 100 W/1000 W x 100 %

Efficiency = 10 %

What is the efficiency of her body when a cyclist expends 1000 w of power to deliver mechanical energy to the bicycle at the rate of 100w?
