Answer:
It should be t = 1.5 seconds if your equation is h(t) = -16*t^2 + 8t + 24
Step-by-step explanation:
h(t) = -16*t^2 + 8t + 24
We want to solve for t when h(t) = 0.
This is a parabolic equation so basically we can use the quadratic formula to solve this.
h(t) = -16*t^2 + 8t + 24
0 = h(t) = -16*t^2 + 8t + 24
take out the 8
0 = -2t^2 + t + 3
0 = -2t*t - 2t + 3t + 3
0 = -2t * (t + 1) + 3*( t + 1)
0 = (-2t + 3) * ( t + 1)
so time cannot be negative, so we choose 0 = (-2t + 3), t = 3/2 seconds
or t = 1.5 seconds

Area,for rectangles is length x width so 2 1/4 inches x 3 1/2 inches is 7 7/8
Convert the timing into hours only:
11:15 = 11.25h
9:45 = 9.75h
11:45 = 11.75h
7:45 = 7.75h
10:45 = 10.75h
To find the average, we need to find the middle of these timing:
11.25 + 9.75 + 11.75 + 7.75 + 10.75 = 51.25
51.25 ÷ 5 = 10.25h = 10:15 am

Answer: The average time it docks is 10:15 am.
