On a different day the athlete used 6000 kJ of energy to evaporate sweat. The athlete's energy intake was 24 000 kJ. Calculate the percentage of the athlete's energy intake used for evaporation of sweat.

To calculate the percentage, we use the formula: Percentage = (Value / Total Value) × 100% In this case: Value = Energy used for evaporation = 6000 kJ Total Value = Total energy intake = 24 000 kJ Percentage = (6000 / 24000) × 100% First, simplify the fraction: 6000 / 24000 = 6 / 24 = 1 / 4 = 0.25 Then, multiply by 100: 0.25 × 100% = 25% So, 25% of the athlete's energy intake was used for evaporation of sweat.
