Question

A parachutist falls at a speed of about 12 miles per hour. Find this speed in feet per second

Answer 1

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
