Question

Point A on a mountain is 6,450 m above the sea
level. Another point B is in a mine 48,600 m below
sea level. Point C is 1,007 m below point B. Find
the distance between the points A and C.​

Answer 1

$Let \: point \:shows : ' O ' \: sea \: level$

$Point \: 'A' \: shows \: above \ : sea \: level\\ = + 6450 \: m$

$Point \: 'B' \: shows \:Below\ : sea \: level\\ = - 48600 \: m$

$Point \: 'C' \: shows \: below \: point \: B \\= -48600 - 1007 \\= - 49607$

$Now, \red{ Distance \: between \: the }\\\red{ the \: points \: A \: and \: C } \\= OA + OC \\= 6450 + 49607 \\= 56056 \: m$
