Solution
From the day on which she walks 500 m to the day on which she
walks 4500 m, Gauravi increases her distance by m}) - m}) =
m}$.
Since Gauravi increases her distance by 500 m each day, then it takes
m}} =
8$ days to increase from 500 m to 4500 m.
Starting from Monday and counting forward by 8 days (which is 1 week and
1 day) gets to Tuesday, and so Gauravi walks exactly 4500 m on a
Tuesday.
