NOT IN RIGHT SECTION SORRY

OpenStudy (davidusa):

near a freeway in dc, there are 2 cell towers 5 miles apart even though they can be 10 miles apart and still cover all the area in between. why are they so close?

OpenStudy (anonymous):

Think of circles. If you draw it out you will see why in fact they are so close.

i learned at school

OpenStudy (anonymous):

Err, fix that for 10 m not 5m lol

OpenStudy (davidusa):

|dw:1386983785918:dw| one tower at each vertex since towers send signals in 3 vague directions

OpenStudy (anonymous):

Also, as the distance from the towers increases, your signal decreases. Maybe that is another cause they are looking for. That is more of a discussion type questions

OpenStudy (davidusa):

most towers are about 10 miles about like those near normal roads

OpenStudy (davidusa):

thanks for helping me. but i still dont understand

OpenStudy (davidusa):

@biggi3lue i still dont understand please help

OpenStudy (anonymous):

I'm thinking. Could you explain from the beginning? As far as I understand, the question is: There are radio towers placed evenly along a straight road, 5miles apart. Their signal reaches up to 10 miles. Why is it done this way? Or am I missing something? What's the hexagon for?

OpenStudy (davidusa):

think of a hexagon. one tower at each point
