(c) 300m
(d) 750m

Can Any Expert please come to Answer This Question..

Answer 1

Resposta:

Item a) 150 m.

Explicação:

The constant speed is represented from t=20s to t=30s and one can just to evaluate the area of a rectangle.

So:

A = B . h = 10 . 15 = 150 m

This is possible because, from de average speed equation, we have:

V = ΔS/Δt  ⇒  ΔS = V . Δt  (a product of speed by time variation)
