Which pair of times has the longest elapsed time between the two times?

11:10 p.m. to 2:15 a.m.

9:15 a.m. to 12:35 p.m.

6:45 p.m. to 10:00 p.m.

3:30 a.m. to 6:15 a.m.

Answer 1

9:15 a.m. to 12:35 p.m.

Explanation:

A: 3 hours and 5 minutes elapsed. (Add 5 minutes to 11:10 to get 11:15, and then you add 3 hours to get 2:15 a.m. Thus, a total of 3 hours and 5 minutes elapsed.)

B: 3 hours and 20 minutes elapsed. (Add 20 minutes to 9:15 to get 9:35, and then you add 3 hours to get to 12:35 p.m. Thus, a total of 3 hours and 20 minutes elapsed.)

C: 3 hours and 15 minutes elapsed. (Add 15 minutes to 6:45 to get 7:00, and then you add 3 hours to get to 10:00 p.m. Thus, a total of 3 hours and 15 minutes elapsed.)

D: 2 hours and 45 minutes elapsed. (Add 45 minutes to 3:30 to get to 4:15, and then you add 2 hours to get to 6:15 a.m. Thus, a total of 2 hours and 45 minutes elapsed.)
