C-4 miles because he’s running from the bike

Answer from: khamani623

Choice B) 3 miles

You have the correct answer. Nice work.

Explanation:

Let's say Phil passes his brother at a sign post, and let's say the sign post is x miles into the 6 mile hike. This means 0 < x < 6.

Once Bill reaches the sign post, he turns around to walk back x miles. His faster brother Phil bikes the remaining 6-x miles to the trail end, before coming back to bike an additional 6 miles to get to the trailhead again. Phil arrives back at the same moment Bill does.

Overall, Phil travels 6-x+6 = 12-x miles in the same amount of time Bill walks back x miles. I recommend drawing out a number line diagram to see why this is the case.

For Bill, we have this equation

distance = rate*time

x = r*t

r = x/t

Phil has the equation

distance = rate*time

12-x = (3r)*t

Notice that Phil's rate is three times that of Bill. The t is the same for both brothers because they travel in the same timespan.

Plug in r = x/t and solve for x. The t variables divide and cancel.

12-x = 3*(r)*t

12-x = 3*(x/t)*t

12-x = 3x

12 = 3x+x

4x = 12

x = 12/4

x = 3

Phil passed Bill at the 3 mile marker.

This is why the answer is choice B.

Answer from: Quest

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

Answer from: Quest

the required function is $y=-x+4$ .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

$m=\frac{y_2-y_1}{x_2-x_1}=\frac{4-7}{)}=\frac{-3}{3}=-1$

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

$y=mx+b$

where, m is slope and b is y-intercept.

$y=-1x+4$

$y=-x+4$

therefore the required function is $y=-x+4$ . the graph of this function is shown below.
