Question
(a) In a number line, there are eight points.They are lying on number line such that US = SR = RT and AP = PQ = QB. Find the rational numbers represented by P, Q, R, S.
(b) Ashley recently opened a store that sells only natural ingredients. She wants to advertise her products by distributing bags of samples in her neighbourhood. It takes one person 2 minutes to prepare one bag.
How many hours will it take to prepare 900 bags of samples if Ashley and 5 of her friends do the work?

Answer:
:
Each part:2 Marks
(a) As given in the question AP = PQ = QB = 13, because interval of one between AB is divided by into three equal parts.
Similarly, US = SR = RT= 13, since the interval of one between U and T is divided into three equal parts.
So, value of P =2+13=73;
Q =73+13=83
Similarly for R =−1−13=−43;
S =−43−13=−53
(b) Time taken by 1 person to prepare 1 bag = 2 minutes
Time taken by 6 people to prepare 1 bag = 26minutes
Time taken by 6 people (Ashley and her 5 friends) to prepare 900 bags
= 26×900=300minutes=5hrs
