Two persons start from the same location O and walk around a square (in horizontal plane) in different directions with constant speeds. The square is 30 m by 30 m . A's speed is $2 m / s$ and B's speed is $1 m / s$ .

Options:(select one or more)

Answer:

A,B,C,D

Solution:

Let A move distance : x ∴ B moves distance : $120 - x$ $x = 2 t$ $120 - x = 1 t$ $120 = 3 t$ $∴ t = 40 s$ $∴ x = 80 m$
