First walk=descend of 1024 feet in 17 minutes
second walk=descend of 500 feet in 7 minutes
so in total she descended 1024+500=1524 feet in 7+17=24 minutes
as an average rate this equals 1524/24=63.5 feet/minute descended
or an average rate of -63.5 feet/minute in altitude (note the minus)
Number = 42
50% of 42
= 50/100 × 42
= 21
Increased number = 42 + 21 = 63
