Problema Solution
Ali was reviewing his family video. The tape totaled 2 hours and 37 minutes. Video of his children totaled 72 minutes. How much of the video was not of his children?
Answer provided by our tutors
The length of the total tape in minutes is:
2*60 + 37 = 157 min
We subtract the 72 minuted of the video with his children from the total length of the tape:
157 - 72 = 85 min = (1*60) + 25 = 1 hr 25 min
1 hour and 25 minutes of the video was not of Ali's children.
