Answer is 3 seconds
When the bullet reaches the ground, ground being x in graph (and here its s which is = 0)
s = -16t^2 + 48t
s = 0, solve for t
0 = -16t^2 + 48t
0 = t ( -16t + 48)
0 = 16t ( - t + 3)
now you have two equation
0 = 16t and 0 = -t +3 ( you can look at the graph line touches x twice)
0 = 16 t
0 = t ( you know its false, because time = 0)
You are left with
0 = -t + 3
t = 3
It takes 3 seconds for the bullet to return to the ground.

Step-by-step explanation:
a. 50 x 9 = 450. A=450
b. I can scale the unit rate of the area given above and largen the area of the map. Ex. =
<---(scaled by 2)
Then we can enlarge it however we want so,
=
<--(scaled by 2 once more)
If the statement above is true then we can scale times 4.
=
<---(scaled by 4)
