A) The speed of the parachute in feet per second is; 198 ft/s
B) At the given speed, the number of feet the parachute will fall during 15 seconds of freefall is; 2970 ft
We are given;
Speed of parachute during freefall = 60 m/s
A) We are told that 1 m = 3.3 ft
Thus, 60 m/s in ft/s = 60 × 3.3/1 = 198 ft/s
B) Speed is now 198 ft/s
Time is 15 seconds
Formula for distance is;
Distance = speed × time
Distance = 198 × 15
Distance = 2970 ft

Answer:
Your answers are:
Step-by-step explanation:
A) 0.5
B) 1/2
How do we get from a decimal to a percent? We multiply by 100. So 0.5 * 100 = 50%. A) is correct.
How do we go from a fraction to a percent? Percent means "out of 100" so a fraction out of 100 is how you can tell if the percent matches the fraction.
1/2 = ?/100
1/2 = 50/100
Half of 100 is 50, so B) is correct.
To save the explanation, C) and D) are incorrect because C) ends up being 5% while D) ends up being 2%.
Your answer is A) and B).
I hope this helps!
