Question

a person moving in a square path of side 10 m and cover 3.75 round calculate the distance and displacement?​

Answer 1

Answer:

distance=150m displacement=10m

Explanation:

in 1 round, distance covered = perimeter of square = 4x10 = 40m

In 3.75 rounds, distance covered = 3.75x40 = 150m

Now if he were to complete 4 rounds, he had to travel 4x40 = 160m

But actual distance is 150m i.e (160-10)m.

This mean that he is one side short of completing the round. So displacement will be 10m.
