x = sqrt{y}k
K is the constant of proportionality.
128 = sqrt{16}k
128 = 4k
128/4 = k
32 = k
x = sqrt{y}k
x = sqrt{36}•32
x = 6 • 32
x = 192
Find y when x = 48.
x = sqrt{y}k
48 = sqrt{y}32
48/32 = sqrt{y}
(48/32)^2 = [sqrt{y}]^2
2.25 = y

Step-by-step explanation:
Answer:
each rest stop is 0.45 inches apart on the new map.
Step-by-step explanation:
First, we need to figure out how long is the highway. since 6/2 = 3, we know that the length of the highway is equal to 45*3. 45*3 = 135.
Now since the beginning stop doesn't count(it's at the 0 miles point and normal dividing would not count 0), so we know that there is 10 stops.
Since on the new map there was 30 miles in a inch, 135 miles on the new map would equal to 4.5 inches(135 = 120+15 = 4*30+0.5*30). 4.5/10 = 0.45 inches. So basically the rest stops are 0.45 inches apart.
