Alek went for a walk. D (t) models the distance Alek walked (in kilometers) after t hours.

What does the statement D (0.5)

Step-by-step explanation:

Given:

D (t) models the distance Alek walked (in kilometers) after t hours.

⟹D (0.5) ⟹D (0.5) is the distance Alek walked after 0.5 hours.

Similarly, D (1) D (1) is the distance Alek walked after 1 hours.

⟹D (1) - D (0.5) ⟹D (1) - D (0.5) is the distance covered by Alek between time t = 0.5 hour and 1 hour.

So, D (0.5)
