Answer:
PLEASE MARK AS THE BRAINLIEST
Explanation:
9) 4 rounds of a track 200
=4 x 200
= 800m
10) when an object is not at motion or if it is not moving it is said to be at rest
11) motion is the action or process of moving or being moved
12) The actual length of the path covered by an object is known as distance
13) Distance can never be negative
14) Rest and motion are relative terms because they depend on the observer's reference
15) Distance is a scalar quantity
Explanation:
9.
When finish line is same as that of initial line , it means length of one round = 2 × Length of track = 2 × 200 = 400 m
total distance covered by athletics = 4 × Length of one round
= 4 × 400
= 1600 m
= 1.6 Km
= 1 mile

A body is said to be at rest if it does not changes its position continuously with respect to its surroundings with the passage of time.
Ex : A book lying on a table.
(11)
A body is said be in a state of motion if it changes its position continuously with respect to its surroundings with the passage of time.
Ex : A bus running on a road.
(12)
Distance is the total movement of an object without any regard to direction.
(13)
Distance cannot be negative.
(14)
Rest and motion are the relative terms because they depend on the observer's frame of reference. So if two different observers are not at rest with respect to each other, then they too get different results when they observe the motion or rest of a body.
(15)
Distance is a scalar quantity
Hope it helps!
