Answer:
The movie was 1 hr 45 mins long.
Amar got home by 8:30 pm
Explanation:
Amar and his friends went to a movie at 5:45 P.M and the movie ended at 7:30 P.M.
The length of the movie can be found by subtracting the start time from the end time of the movie:
H M
07 : 30
- 05 : 45
01 : 45
The movie was 1 hr 45 mins long.
Amar got home 45 minutes after the movie ended.
We simply add 45 minutes to 7:30 pm:
H M
07 : 30
+ 00 : 45
08 : 15
Amar got home by 8:15 pm.
