Question

Joe is hiking in national park wilderness. His radio transmits signals as far as the horizon. Use the formula d =Square root/1.5h , where d is the line-of-sight distance to the horizon in miles and h is height in feet.
Joe sets his receiver on the ground. What is the farthest away that a transmitter 4 ft above the ground can be in order to reach Joe?

a.
0 mi
c.
2.4 mi
b.
1.2 mi
d.
6 mi

Answer 1

D=√(1.5)(1.4)
d= √6
d= 2.44948.....

Rounded to the nearest tenth would be c. 2.4 mi
