So in 1 hour, the parachutist will fall 12 miles or
12 mi/1hour
convert
1 hour=60 mins
1 min=60 seconds
1 hour=60 times 60 seconds=360 seconds
12 miles per 360 seconds
convert miles to feet
5280 feet per mile
12 miles times 5280=63360 feet
63360/360
do the math and simplify
63360/360=6336/36=176
176 feet per second
To find the percentage, you divide the new price ($39.90) by the original price ($38), and the multiply it by 100 to change the answer from a decimal to a percentage:
39.90 / 38 x 100 = 105
So 39.90 is 105% of 38
To get our final answer, subtract this by 100%
105 - 100 = 5%
ANSWER: So the percentage increase of the price is 5% ($1.90)
