Question 127638
The observation point, the point directly below and the
height of the ballon form a right triangle. The distance
from the observer to the ballon is the hypotenuse
{{{d = sqrt(h^2 + 125^2)}}}where distances are in meters
The ballon is going up at a rate of 4 m/sec. If {{{t}}}
is the elapsed time, {{{h = 4t}}}where {{{t}}}is in seconds
and {{{h}}} is in meters.
{{{d = sqrt((4t)^2 + 125^2)}}}
{{{d = sqrt(16t^2 + 15625)}}} meters answer
