Answer:
<u>Option D : c =200t</u>
Step-by-step explanation:
The number of calories burned C varies directly with the time spent exercising T
∴ ∝ t
∴ c = a t
Where a is the constant of proportion
exercising for 4 hours he burns 800 calories
∴ c = 800 when t = 4
∴ 800 = 4 a
∴ a = 800/4 = 200
∴ c = 200 t
<u>The answer is option D : c =200t</u>
