<PRE><B>Question 1107549</B>
horses age more rapidly than humans supposed that the horses age and human age very directly and supposed to a five-year-old horses equivalent to a 15 year old human find the equivalent human age for a horse who has lived 16 years 
-------------------
Since they are directly related,
human = k*horse
--
Solve for &quot;k&quot;
15 = k*5
k = 3
------
Equation::
human = 3*horse
--
Your problem::
human = 3*16 = 48 years
