This is from a website, because I can't explain it very well. With the below information, it makes me think the answer is B. Here's the information provided from a website with a few modifications to it to be more organized:
"
16t^2 = 1551
16t^2/ 16 = 1551/16
t^2 = 96.93
t = 9.8 sec
"
I hope this helps! :)
When a skydiver jumps from an airplane, the distance d in feet the diver falls in t seconds before opening the parachute is given by the formula d=16t^2. The formula assumes that there is no air resistance. Find the time it takes a skydiver to fall 1,551 ft before opening the parachute. Round to the nearest tenth.
A. 9.7 s
B. 9.8 s
C. 9.9 s
D. 2.5 s
