Question

If a person's eye level is h meters above sea level and he can see d kilometers to the horizon, then d=3.57h. Suppose the person's eye level is 15.21 meters

above sea level. How far can he see to the horizon?

Round your answer to the nearest tenth.

Answer 1

d = 7.5

Explanation:

d = 3.57
`√(h)`

= 3.57
`√(4.41)`

= 3.57( 2.1)

= 7.497

d = 7.5!

Answer 2

54.3m

Explanation:

h = distance above sea level

d = distance he can sea above sea level

d = 3.57h

h = 15.21m

d = ?

d = 3.57 × 15.21

d = 54.2997m approximately 54.3m

The person can see up to a distance of 54.3m
