Question

Brenda set her watch 14 seconds behind, and it falls behind another 1 second every day. How far behind is Brenda's watch if she last set it 13 days ago?

Answer 1

So it's already 14 seconds behind, we know that, and every day it is +1 and we know that there has been 13 days so 13 times 1 is 13 plus the 14 seconds that were already behind so 13 plus 14 is 27, 27 seconds behind
