Can someone help me with this math word problem please?

Question

According to the 1998 Guinness Book of World Records stuntman Dan Koko fell a distance of 332 feet into an airbag after jumping from the Vegas World Hotel and Casino. The distance d in feet traveled by a freefalling object in t seconds is given by the formula d = 16t 2. To the nearest tenth of a second, how long did the stuntman's freefall last?

Answer 1

4.6 seconds answer mine

Answer 2

d = 16t^2

332 = 16t^2

332/16 = t^2

20.75 = t^2

t = +- sqrt(20.75)

t = +- 4.5552

Since we're dealing with time, we can neglect the -ve root, and the answer to the nearest tenth of a second is 4.6s

Answer 3

im assuming the 2 means squared here.

just plug in the info you were given and boom.

332 = 16t^2

Divide 16 both sides.

20.75 = t^2

sqrt 20.75 = t

t = 4.6 seconds

Answer 4

d=16t^2

when d = 332 feet

332 = 16t^2

332/16 = t^2

20.75 = t^2

t = SQRT 20.75

t = 4.55521679 seconds

therefor t = 4.55521679 rounded to nearest tenth of a second the fall lasted 4.6 seconds

Answer 5

Simply plug 332 feet in for d.

332=16t*2

332=32t

10.375=t

10.4 seconds =t

Edit: Was the two an exponent or were you multiplying 16t by 2?
