40度15’27’’-13度26’37’’是一道计算题.

问题描述:

40度15’27’’-13度26’37’’
是一道计算题.

40度15’27’’-13度26’37’’
算式变成:
40°15′27〃-13°26′37〃
=39°74′87〃-13°26′37〃
=26°48′50〃

26'38'50

40度15’27’’-13度26’37’’
=39度75’27’’-13度26’37’’
=39度74’87’’-13度26’37’’
=26度48’50’’

在数学中1°=60′,1′=60〃,那么算式变成:
40°15′27〃-13°26′37〃
=39°75′27〃-13°26′27〃
=39°74′87〃-13°26′37〃
=26°48′50〃
