Question

1. A worker covers a distance of 40 km from his house to his place
of work, and 10 km towards his house back. Then the
displacement covered by the worker in the whole trip is​

Answer 1

Given:

Distance covered by the worker from his house to his place of work = 40 km

And then distance covered towards his house back = 10 km

To find:

The displacement covered by the worker in the whole trip = ?

Solution:

First of all, let us learn about the concept of displacement.

Displacement is the minimum distance between the starting and the ending point of the object.

Displacement of any object is always lesser than or equal to the total distance covered. It can never be greater than the distance covered.

Now, please refer to the attached diagram for the representation of the given question statement.

In the present case, total distance covered = AB +BC = 40 km + 10 km = 50 km

As per the question statement, the worker goes back towards his home for 10 kms.

So, the displacement, AC = AB - BC = 40km - 10 km = 30 km
