Answer:
900 m ( 0.9 km)
Explanation:
from the question we have the following
first person's height (h) = 100 m above the earths surface
distance to the horizon that can be seen (s) = 15 km = 15,000 m
second person's height (h1) = 36 m
distance to the horizon that can be seen (s1) = ?
take note that the distance (s) a person can see = square root of the person's height
s = x K
where k is a constant
from the height and the distance the first person can see we can get the value of K
15000 = x K
15000 = 10 x K
K = 150
now putting the value of K and the height of the second person into the equation we can get the distance into the horizon the person can see
s = x 150
s = 900 m
therefore the second person who is 36 m above the surface can see 900 m ( 0.9 km) into the horizon
