Answer:
y = -40x+2600
Step-by-step explanation:
Writing the values as coordinate (m, s)
If after flying for 11 seconds, he is 2160 meters from her, the required coordinate is (11, 2160)
Then at 19 seconds he is 1840 meters, the required coordinate is (19, 1840)
Get the slope;
m = 2160-1840/11-19
m = 320/-8
m = -40
Substitute m = -40 and (11, 2160) into the equations;
y-y0 = m(x-x0)
y -2160 = -40(x-11)
y - 2160 = -40x+440
y = -40x+440 + 2160
y = -40x+2600
Hence the requires equation is y = -40x+2600
So, there is a rectangular park with longer side (length) 150 yards and shorter side (width) 125 yards.
so walking around the rectangular park once is like covering the Perimeter (p) of the rectangular park.
So, lets find the perimeter of the park.
Perimeter of rectangle = 2 ( l + w)
= 2 ( 150 + 125 )
= 2 * 275
= 550 yards
Now, walking around the park two times is like doubling the Perimeter of the rectangle. So, when Debbie walks around the park 2 times, he covers the perimeter of the rectangular field twice.
i.e. Debbie walked 2 * Perimeter
= 2 * 550
= 1100 yards
Now, If Debbie wanted to walk 1,000,000 yards, she has to walk the rectangular park (1,000,000 / the Perimeter of the park)
i.e. 1,000,000 / 550
= 1818.18 times
So,
(a) she walks 1100 yards
(b) She have to walk 1818.18 times
The answer rounded would be .83. I got this by writing out the equation each hour. For example, 1/2+1/2+1/2+1/2+6+1/2+1/2+1/2+1/2+0+0+0 = 10. Then, to find the average you divide them out by the amount of numbers. This would give you 10 divided by 12.
