<PRE><B>Question 171994</B>
d = 1.3 sqrt h, where h is the height in feet above the surface. How high (to the nearest foot) would a platform have to be to see a distance of 13.5 miles?
------------------------
13.5 = 1.3*sqrt(h)
sqrt(h) = 13.5/1.3
h = (13.5/1.3)^2
h = 108 feet
-------------------
knightowltutor converted from miles to feet, but the eqn says d is in miles.
