Answer:

0.1 hours to the nearest tenth (0.125 hours exact)

Step-by-step explanation:

For this problem, we simply need to do a conversion to find the length of time.

We are given the rate 40 miles per hour, and the distance of 5 miles. We simply need to know the amount of time.

5 miles * (1 hour per 40 miles) = 1 hour / 8

Note, the distance unit cancels out.

So, to travel 5 miles it will take 1/8 of an hour.

1/8 as a decimal is equal to 0.125. The answer rounded to the nearest tenth would be 0.1 hours, since the 2 rounds down.

Cheers.

If the grist mill completes the rotation in 8 seconds. Then the final position of the bucket after 6 seconds is (0, 9).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0).

Then the coordinates of the bucket's location after 6 seconds will be

The angle of rotation after 6 seconds will be

$\rightarrow \dfrac{6}{8} \times 360\\\\\rightarrow 270^o$
