Monrovia Liberia is the closest place in Africa to Recife Brasil. The distance from Recife Brasil to Monrovia Liberia, is 3000 + km. This was calculated this morning by using my Grade 3 wooden with notched edges, the result of numerous hand-to-hand duels at the back of the classroom, whilst Sammy Johnson, our war WWII vetran teacher was in the storeroom having a quick puff at a butt end of a cigarette and a swig of Montville sherry to give him courage to face the children in the second hour of the morning. The 'I love Theresa 4 ever', carefully compas-scratched with diligence, deep affection and inked deep with red-for-love ink still brings back the memories of a heart-fluttering childhood. Oh how I wish... I digress... .............................. Height of Recife . Altitude: 16 metros www.pousadapeter.com.br/olinda.htm 'Imagine you were standing at an elevation of h meters above the ocean and looking out across the water. What is the distance D to the horizon? If you are standing atop a mountain 1 km high, h = 1 km and your horizon should be 112.88 km away (we neglect the refraction of light in the atmosphere, which may modify this value).' http://www-istp.gsfc.nasa.gov/stargaze/Shorizon.htm Recife is 16 metros above sea level. So the distance from the horizon is 1/16th of 112.88 km which is 7.055km. Answer to the question is no. Hugs ruler an carefully snuggles it into a warm and perfectly folded piece of soft red woollen felt. Goes to bed for pleasant dreams. Wonders... Why the hell I did I ever marry Charlie ?
