Question

On a sports day,in a rectangular field ABCD lines were drawn with chalk powder at a
distance of 1m each. 100 flower pots have been placed at a distance of 1m from each other
along AD as shown in the figure:

Anitha and Babitha started the final race. After 5 minutes Anitha covered 1/10th of the track
on the second line along AD, while babitha covered 1/5th of track on the 8th line along AD
after which Anitha fell down. Babitha then stopped and approached to help Anitha.

i. Considering A as the origin, what are the coordinates of A? (1)
a) (0,1) b) (1,0) c) (0,0) d)(-1,-1)

ii.What are the coordinates of B? (1)
a)(0,11) b)(11,0) c)(0,0) d)(1,11)

iii. What is the coordinate of the position of Anitha after 5minutes? (1)
a)(0,6) b)(2,6) c)(6,2) d)(2,0)


iv. What is the coordinate of the position of Babitha after 5minutes? (1)
a)(8,0) b)(5,8) c)(8,5) d)(0,5)

v. How much distance Babitha has to run to help Anitha? (1)
a) 37 units b)√37 units c) 6units d) 36units

I) (0,0)

• Mathematics is the science that deals with the logic of shape, quantity and arrangement. Math is all around us, in everything we do. It is the building block for everything in our daily lives, including mobile devices, architecture (ancient and modern), art, money, engineering, and even sports.
• Since the beginning of recorded history, mathematic discovery has been at the forefront of every civilized society, and in use in even the most primitive of cultures. The needs of math arose based on the wants of society.

Answer 2

Answer:

Step-by-step explanation

i) consider A as the origin the coordinates will be (0,0) irrespective of what the origin is named.

ii) The coordinates of B will be (0,11)

iii)The coordinates will be (2,6) since anitha has fell down here

iv) The coordinates will be (8,5)

v) The answer here is 6 units.
