Answer:

It would take
2.7 seconds, correct to 1 decimal place/nearest tenth.

Explanation:

Step 1: Understanding the formula

The formula is given as
h=16t^(2), where
h represents the height, and
t represents the time.

Step 2: Substituting and solving

The question asks for the time that would take when the height is
117~\text{feet}.

So, substitute
117 for
h in the formula, since
h denotes the height:


h=16t^(2)\\117=16t^(2)

Now, let's solve the equation to find the time,
t:


117=16t^(2)\\\\\text{Divide by 16 on both sides of the equation:}\\(117)/(16)=(16t^(2))/(16)\\\\\text{Simplify:}\\7.3125=t^(2)\\\\\text{Square root both sides of the equation:}\\√(7.3125)=\sqrt{t^(2)}\\\\\text{Calculate:}\\2.7 \approx t\\\\\text{Rearrange the equation:}\\t\approx2.7

So, it takes about
2.7 seconds to travel
117 feet, according to the formula.
