Option D.
Step-by-step explanation:
We have to calculate the elapsed time between 2:16 A.M. and 8:10 P.M.
First we convert time in 24 hour format.
2:16 A.M. = 2:16
8:10 P.M. = 20:10
Now subtract to get the elapsed time.
Hour Min.
20 10
- 2 16
17 54
The elapsed time is 17 hours 54 minutes.
Option D. is the answer.
