Answer:
18 days
Step-by-step explanation:
Let x represent number of days.
We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall seconds behind in x days.
We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total seconds in x days.
Since Brady's watch is 22 seconds behind, so we will equate by 22 to solve for x as:
Therefore, Brandy set her watch 18 days ago.
