Problem

Each day Maria must work $8$ hours(LOL). This does not include the $45$ minutes(People just buy a sandwich and eat at their desks these days) she takes for lunch. If she begins working at $\text{7:25 A.M.}$ and takes her lunch break at noon(you mean lunch time), then her working day will end at night.

$\text{(A)}\ \text{3:40 P.M.} \qquad \text{(B)}\ \text{3:55 P.M.} \qquad \text{(C)}\ \text{4:10 P.M.} \qquad \text{(D)}\ \text{4:25 P.M.} \qquad \text{(E)}\ \text{4:40 P.M.}$

Solution

8 hours from 7:25 AM is 15:25 or 3:25 PM. 45 minutes from 25 minutes is 10 minutes after the hour, so her working day ends at $\boxed{\text{(C)}\ \text{4:10 P.M.}}$
