Question

Alan set his watch 13 seconds behind, and it falls behind another 1 second every day. How

many days has it been since Alan last set his watch if the watch is 35 seconds behind?

Answer 1

31 additional days, getting behind by 31 seconds; this, added to the original 4 sec behind, gives you a total 35 seconds behind.

Now, that really isn't complicated, right?

Answer 2

it would be 22 days.
