3.1 Determine how many calories will a male tennis player with 83,5kg in one hour
3.2 A male tennis player with a weight of 83,5kg will lose than 0,077kg , if he plays consistently the tennis game.
Verify this statement showing all calculations if one gram = 9 calories
3.3 Calculate the number of hours a tennis player needs to play in order to lose 1600 calories
3.1 To determine how many calories a male tennis player with a weight of 83.5kg will burn in one hour, we can use a proportional equation:
Calories burned = (Weight2 / Weight1) x Calories burned1
Let Weight1 = 70kg and Calories burned1 = 583 calories per hour.
Weight2 = 83.5kg.
Calories burned = (83.5 / 70) x 583
= 1.1929 x 583
= 694.2067 (approximately)
Therefore, a male tennis player with a weight of 83.5kg will burn approximately 694 calories in one hour of tennis.
3.2 To determine how much weight a male tennis player with a weight of 83.5kg would lose if he consistently played tennis, we can use the equation:
Weight loss = (Calories burned / Calories per gram)
Calories burned = 694 (from the previous calculation)
Calories per gram = 9 (given)
Weight loss = 694 / 9
= 77.11 grams (approximately)
Therefore, the male tennis player would lose approximately 77.11 grams of weight if he played consistently.
3.3 To calculate the number of hours a tennis player needs to play in order to lose 1600 calories, we can use the equation:
Number of hours = Calories to lose / Calories burned per hour
Calories to lose = 1600
Calories burned per hour = 583 (given)
Number of hours = 1600 / 583
= 2.75 (approximately)
Therefore, a tennis player would need to play for approximately 2.75 hours to burn 1600 calories.
