"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 help break this down for me, I'd greatly appreciate it. :)
