Answer:
The part of the video that was not of his children is:
85 minutes OR 1 hour and 25 minutes.
Step-by-step explanation:
It is given that:
Ali was reviewing his family video.
The tape totaled 2 hours and 37 minutes.
Now we know that:
1 hour=60 minutes
This means that:
2 hours=2×60 minutes
i.e.
2 hours= 120 minutes
Hence, 2 hours and 37 minutes= 120+37 minutes
i.e.
2 hours and 37 minutes= 157 minutes.
Video of his children totaled 72 minutes.
This means that the part of the video not of his children is:
Total time of video-Time of video of his children
= 157-72
= 85 minutes or 1 hour and 25 minutes
