38) Manpreet Kaur is the national record
holder for women in the shot-put discipline. Her throw of 18.86m at the Asian
Grand Prix in 2017 is the maximum distance for an Indian female athlete.
Keeping her as a role model, Sanjitha is determined to earn gold in Olympics
one day. Initially her throw reached 7.56m only. Being an athlete in school,
she regularly practiced both in the mornings and in the evenings and was able
to improve the distance by 9cm every week. During the special camp for 15 days,
she started with 40 throws and every day kept increasing the number of throws
by 12 to achieve this remarkable progress.
(i)
How many throws Sanjitha practiced on 11th day of the camp?
(ii)
What would be Sanjitha’s throw distance at the end of 6 weeks?
(or)
When will she be able to achieve a throw of
11.16 m?
(iii)
How many throws did she do during the entire camp of 15 days ?
