Answer:
It can record 198 mintues on extra-long play
Step-by-step explanation:
The full battery(100%) of the videotape is:
2 hours(120 minutes) on short play
4 hours(240 minutes) on long play
6 hours(360 minutes) on extra long play.
32 minutes on short play
It used 32/120 = 0.2667 of the battery
44 minutes on long play
it used 44/240 = 0.1833 of the battery
Battery used:
0.2667 + 0.1833 = 0.45
Battery remaining
1 - 0.45 = 0.55
Out of 6 hours(360) on long play
0.55*360 = 198
It can record 198 mintues on extra-long play
