Question

In the grid shown below, ten points are marked (a to j). Using the figures marked with the grid, identify the latitudes and longitudes of these points.

${40}^o$	${30}^o$	${20}^o$	${10}^o$	$0^o$	${10}^o$	${20}^o$	${30}^o$
${30}^o$				$b$
${20}^o$							$j$
${10}^o$	$e$				$f$
$0^o$		$a$		$g$		$d$
${10}^o$							$i$
${20}^o$			$c$
${30}^o$							$h$

Answer 1

Point	Latitude	Longitude
a	$0^o$	${20}^{o}W$
b	${30}^{o}N$	$0^o$
c	${20}^{o}S$	${10}^{o}W$
d	$0^o$	${20}^{o}E$
e	${10}^{o}N$	${30}^{o}W$
f	${10}^{o}N$	${10}^{o}E$
g	$0^o$	$0^o$
h	${40}^{o}S$	${40}^{o}W$
i	${10}^{o}S$	${20}^{o}E$
j	${20}^{o}N$	${30}^{o}E$
