If a person's eye level is h meters above sea level and she can see d kilometers to the horizon, then d = 3.6√h . Suppose the person can see 24.3 kilometers to the horizon.

Question

What is the height of her eye level above sea level? Carry your intermediate computations to at least four decimal places, and round your answer to the nearest tenth.

Answer 1

3.6√h = 24.3 Kilometers

√h = 6,750 Kilometers

h = 45.5625 Kilometers above sea level

h = 45.6 Kilometers above sea level rounded

Answer 2

d = 3.6√h

24.3 = 3.6√h

Solve for h. Note that the units are meters, not kilometers..
