peter weighs 105kg. He wants to lose 500mg per week. how many weeks will it take to reach 90kg. Explain

 

GIVEN:

m = 105 kg

500 mg/wk = 0.0005 kg/wk

DESIRED AMOUNT:

90 kg

SOLUTION:

105 kg – 90 kg = 15 kg

(0.0005 kg/wk) x (10000/10000) = 5 kg/10000 wk

15 kg / 5 kg = 3 kg

(5 kg/10000 wk) x (3/3)

15 kg/30000 wk.

ANSWER:

Peter needs to take 30,000 weeks to reach 90 kg.

(NOTE: Now, I am confused. The question ia quite unrealistic....If I were Peter, then I would increase my weight loss every week.)
