Materi : tenaga pembentuk muka bumi
Kls : x
Pembahasan :
8) =>
(a) delta t = {(s-p) - 1' } ×1 mg.
= {(05.35.42 - 05.35.12)-1') × 1000 km
= {( 00.00.30) -1'} ×1000 km
=| 0,5'-1'| × 1000 km
= 0,5 × 1000 km
= 500 km

(b) delta t = {(s-p) -1'} ×1 mg.
= {(05.41.42 -05.40.22)-1'} ×1000 km
= {(01.20)-1'} ×1000 km.
= { 1,33' -1'}× 1000km
=0,33 × 1000 km
= 33 km
