"a parachutist's rate during a free fall reaches 80 meters per second. what is this rate in feet per second? at this rate, how many feet will the parachutist fall during 20 seconds of free fall? in your computations, assume that 1 meter is equal to 3.3 feet. do not round your answers." i'm suppose to find the rate in ft/s and "distance in 20 seconds" in ft. if anyone can break this down for me, i'd greatly appreciate it. : )

Ответ:
a)264 feet/ second
b)5280 feet during 20 seconds
Step-by-step explanation:
A parachutist's rate during a free fall reaches 80 meters per second.
Convert the rate in feet per second
We are given that meter is equal to 3.3 feet
So, So, rate in feet per second =
So, parachutist fall in 1 second = 264 feet
Parachutist fall in 20 second =
Hence the parachutist will fall 5280 feet during 20 seconds of free fall
Ответ:
Glasses were $2
I used the elimination method. I multiplied everything in the equation that represents the second order by five and subtracted it from the first orders equation. I then solved for y and got that each glass was $2. I then plugged the 2 back into the original equation to find that a centerpiece was $40.
