Question

A person goes around the perimeter of a square park in exactly 1 minute. Each side of the park

measures 15 m. What will be the average velocity of the person after three and a half minutes?​

Answer 1

Answer:

30 root 2/7 m/min

Explanation:

Displacement means the shortest distance

So after 3and a half minutes he completes 3 rounds and a half round

That is if he starts from a corner he reaches exactly to the opposite corner i.e, diagonally

So,

A right triangle will be formed,

The hypotenuse is the displacement which is

Root 15^2+15^2=root 450= 15 root 2

Average velocity =15 root 2 / 7/2

=30root2/7 m/min

Check the units they are in m/min
