उत्तर
Paheli moves on a straight road from point A to point C. She takes 20 minutes to cover a certain distance AB and 30 minutes to cover the rest of distance BC. She then turns back and takes 30 minutes to cover the distance CB and 20 minutes to cover the rest of the distance to her starting point. She makes 5 rounds on the road the same way. Paheli concludes that her motion is rectilinear and periodic both.
Explanation:
Paheli is moving along a straight line, so her motion is rectilinear and she is also moving with a fixed time period, so her motion is periodic. Therefore, the correct answer is both rectilinear and periodic.
