<h2>First Question:</h2><h3>Given: </h3>
2 km = 1 cm
<h3>To Find:</h3>
The length of the road of 15 km.
<h3>Solution:</h3>
2 km = 1 cm
1 km = 1/2 = 0.5 cm
15 km = 0.5 × 15 = 7.5
<h2>Answer: </h2>
The length of the road is <u>7.5 cm</u>.
Therefore, <u>Option D. 7.5 cm</u> is correct.

Answer:
4
-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4( - 4x + 4) - 8 = 4 - 16x + 16 - 8 = 4 - 16x + 8.
Step-by-step explanation:
1 km = 1000 m
(hence the term "kilo" which means 1000).
so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.
now, we can see the solution already with our eyes.
but let's do it formally :
the rate or ratio between time and distance must be the same for the same speed.
so,
3 min / 1000 m = x min / 500 m
500 m × 3 min / 1000 m = x min
1/2 × 3 min = x min
3/2 = 1.5 min = x min
so, it takes him 1.5 minutes (90 seconds) to run 500 m.
