Question

a body travels along the boundary if a square park with a uniform speed of 4m/s. if the side length of the square park is 20m, find average velocity if he travels for 12s.​

Answer 1

Answer:

48m

Explanation:

NOTE Here the terms velocity and speed are interchangeable.

Total distance travelled = The perimeter of the square

$4 \times side \\ 4 \times 20m \\ 80m$

In 1 second distance travelled is 4m.

Therefore in 12 second , distance travelled is

$4m \times 12sec \\ 48m$
