Arun is participating in an 8 miles walk. The organizers used a square coordinate grid to
plot the course. The starting point is at A (3, 1). At B (3, 4), there's a water station to make
sure the walkers stay hydrated.
From water station, the walkway turns right and at C (6,4) a garden is situated to keep
walkers fresh. From the garden, the walkway turns left and finally, Arun reaches at
destination D to complete 8 miles.
i How far is the water station B fro the starting point A?
a. 4 miles
b. 3 miles
C. 1 mile
d. 5 miles
ii. How far is the water station B from garden C?
a. 3 miles
b. 4 miles
c 1 mile
d. 5 miles
iii. What is the abscissa of destination point D?
Answers
Given :
Arun is participating in an 8 miles walk. The organizers used a square coordinate grid to plot the course
Starting point A ( 3 , 1)
Water station B(3,4)
C (6,4) garden
Destination D ( 8, 4)
To Find : How far is the water station B from the starting point A
How far is the water station B from garden C?
. What is the abscissa of destination point D?
Solution:
water station B from the starting point A
A ( 3 , 1) B(3,4)
= √(3 - 3)² + (4 - 1)²
= √0 + 3²
= 3 miles
Water station B from garden C
B(3,4) , C (6,4)
= √(6 - 3)² + (4 -4)²
= √3² + 0
= 3 miles
abscissa of destination point D ( 8 , 4)
= 8
