Question 1196923
.
A turtle is walking around the perimeter of a fountain, starting at point A as shown. 
It takes the turtle 22 seconds to walk to point B, which is at angle of 24° 
from the starting point. At this rate, how much longer will it take for the turtle 
to reach point C, which is exactly half-way around the perimeter of the fountain?

        Hello, when you say  " . . . point  C,  which is exactly half-way around the perimeter of the fountain? ",

        it is not a definitive description of point  C.


        You should say  " half-way around the perimeter starting from point  A  or from point  B ".


        I will interpret it as if point C is half-way around the perimeter starting from point  A.



<pre>
Let T be this additional time for the turtle to get from B to C.

The arc BC is 180° - 24° = 156°.


Use the proportion  {{{156/24}}} = {{{T/22}}}.


From the proportion, find  T = {{{(156*22)/24}}} = 143 seconds.


<U>ANSWER</U>.  143 seconds to get from B to C.

Solved.


Is everything clear to you ?
