The speed in feet per second is 247.5
The parachutist will fall 4950 feet during 20 seconds.
Step-by-step explanation:
Given,
Speed during free fall = 75 meters per second
It is given that,
1 meter = 3.3 feet
75 meter = 75*3.3 = 247.5 feet
Therefore;
Speed during free fall in feet = 247.5 feet per second
Now,
1 second = 247.5 feet
20 seconds = 247.5*20 = 4950 feet
Fall during 20 seconds = 4950 feet
The parachutist will fall 4950 feet during 20 seconds.
