Vera's phone battery is currently at 1/2 remaining.
1 hour = 1/8.
To determine how many hours remain, divide 1/2 by 1/8 since you wish to figure out how many eighths of battery are left before depletion.
1/2 divided by 1/8 equals 4.
So, there are 4 hours left
I’m not really certain, but I think C could be the answer; my apologies if that's inaccurate.
Mel descends 50-35=15 feet in 5-2=3 seconds. Thus, her descent rate is 15/3=5 ft/sec.
Victor descends 60-50=10 feet in 4-1=3 seconds. Hence, his descent rate is 10/3=3⅓ ft/sec. Mel is faster, traveling at 5 ft/sec.
