<span>For the answer to this question,
Let x = depth of the gutter
then
18 - 2x = width of the gutter
Cross section area
A = depth x width
</span><span> = x(18 - 2x)
A = 18x - 2x^2
:
Axis of symmetry will give x value for max area:
x = -b/(2a)
x = -18/(2x(-2))
x = 4.5 inches is the depth for max area
</span><span>Max area: 4.5 * 9 = 40.5 sq/in
I hope my answer helped you.</span>

Hello!
First you find how far he went
So he we 96 kilometers there and back
96 + 96 = 192
It took him 8 hours to go 192 kilometers
To find the average speed you divide these two
192/8 = 24
So his average speed was 24 kilometers an hour
The answer is 24
Hope this helps!
