Answer:
22 November
Step-by-step explanation:
First we have to find the total length she swims in 1 day
= 2(length of the swimming pool) x no. of lengths she swims in 1 day
=2x30x20
=120m she covers in 1 day
10km = 10,000m
no of days= total distance/ distance she covers in 1 day
=10000/120
=83.3 days
