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!
A full rotation is 360 degrees so the required angle is 360/12 = 30 degrees.
Answer:
9/16 m.
Step-by-step explanation:
When you cut two pieces along its diagonal it causes it to be two congruent triangular pieces.
<em>You need to multiply the length and the width to find an area:
</em>
1 1/2 × 3/4
<em>Now you need to change it into an improper fraction:</em>
1*2+1 = 2+1 = 3; this gives us 3/2:
3/2 × 3/4 = 9/8 = 1 1/8
<em>Dividing it by 2:</em>
9/8 ÷ 2
The distance between the boat and the ocean's floor is 19m

How to get the distance from the ship to the ocean's floor?</h3>
We can see this as a right triangle, where the rope with the anchor is the hypotenuse. So we already know that the hypotenuse measures 30m.
We also know an angle, it measures 39°, and we want to get the opposite cathetus to said angle (the height).
Then we use the relation:
Sin(a) = (opposite cathetus)/(hypotenuse).
Replacing the values that we know, we get:
Sin(39°) = d/30m
sin(39°)*30m = d = 18.9m ≈ 19m
The distance between the boat and the ocean's floor is 19m.
