Answer:
When 2 people work together the total time equals
Total Time = Time 1 * Time 2 / (Time 1 + Time 2)
Let's solve for Time 1 (which will be Tim's time.)
7 hours = Time 1 * 9 / (Time 1 + 9)
7 * Time 1 + 63 = Time 1 * 9
63 = 2 * Time 1
Time 1 = 30.5 Hours (Tim's Time)
Double Check
Total = 30.5 * 9 / (30.5 + 9)
Total = 274.5 / 39.5
Total = 7 Hours
Again, Tim's Time is 30.5 Hours

Correct!
The slope is (14-6)/(9-5) = 8/4 = 2;
<span>the slope-intercept form of the function that contains the points (5, 6) and (9, 14) is y - 6 = 2( x - 5 );
Then, y - 6 =2x - 10;
y = 2x - 4 ;</span>
Interpreting (1,15) with (4,60), found that (4,60) is 4 times of the coordinate (1,15).
<h3>What are coordinates?</h3>
A pair of numbers that describe the position of a point on a coordinate plane by using the horizontal and vertical distances from the two reference axes.
For interpreting we have to find the relation between (1,15) and (4,60)
We have, (1,15)
For x- coordinate 1, y- coordinate will be 15
Now,
let us take x- coordinate=2 then y- coordinate =30
again, if x-coordinate = 3 then y-coordinate = 45
lastly, if the x-coordinate =4 then y-coordinate = 60
That means (4,60) is the 4 times of the coordinate (1,15) i.e., the x-coordinate is 4 times as well as the y- coordinate is 4 times.

Answer:
v = 96 km/h
Step-by-step explanation:
Data:
d = 240 km
t = 2.5 h
speed = d/t
speed = 240/2.5 = 96 km/h
