Answer:
She will arrive at 3:23 to the pool.
Explanation:
Since Natasha takes 33 minutes to walk through the pool from her house.
Also, if she rides a bike then that time is 1/3 times reduced.
So total time to ride the bike from her house to the pool is
![33*(1)/(3)=11 minutes](https://img.qammunity.org/2020/formulas/mathematics/high-school/h4gl3x9bzptsjgdb7qa4c78qmp6v8adyt8.png)
Now, If she leaves the house at 3:12 then she will reach to the pool is 3 hours 12 minutes + 11 minutes = 3 hours 23 minutes = 3:13
Hence, She will arrive pool at 3:23.
