Distance = rate*time, or
distance = (average speed)* time, so
average speed = distance/ time.
average speed = 205 mi / (3/12) h = 205 mi/ (1/4)h = 205*4 mi/h=
= 820 mi/h
It is looks to high for speed of the truck,
probably time should be 3.12 h,
then
average speed = 205 mi / (3.12) h ≈ 65.71 mi/h.
That looks close to real life.

Volume of cone:
-------------------------------------------------
Volume = 1/3 πr²h
-------------------------------------------------
Find Height:
-------------------------------------------------
Given that the radius = 5 and the volume = 100, we will substitute these values into their respective variable and solve for height.
Volume = 1/3 πr²h
100 = 1/3 π (5)²h
h = 100 ÷ 1/3π(25)
h= 4 units (Nearest whole number)
-------------------------------------------------
Answer: The height is 4 units.
-------------------------------------------------
The decimal is 0.9 and the fraction is 9/10
The answer is A. I calculated the answer by using the formula for triangles.
