Answer 1

Answer:

$\frac{V1 + V2}{2}$

Explanation:

Let total time taken be 2t

For the first half ,

• time = 2t/2 = t
• velocity = V₁
• distance = S₁ = V₁ × t

For the second half,

• time = 2t/2 = t
• velocity = V₂
• distance = S₂ = V₂ × t

∴ Average velocity (V) =

$\frac{S1 + S2}{t + t} \\=\frac{V1t+ V2t}{2t} \\= \frac{V1 + V2}{2}$
