Question 1154731: The higher a lookout tower is built, the farther an observer can see. That distance d (called the horizon distance, measured in miles) is related to the height h of the observer (measured in feet) by the formula
d = 1.4
h
.
How tall (in ft) must a lookout tower be to see the edge of the forest, 40 miles away? (Round your answer to the nearest foot.)

given:
d+=+1.4h
d=40 miles
so,
d+=+1.4h
40=+1.4h
h=40%2F1.4
h=28.57
h=29feet
