yang tau tolong yaa, terutama no 3 dan 4

3.) 3 jam = 3 × 60 = 180'
180' + 52' = 232'
2 jam = 2 × 60 = 120'
120' + 49' = 169'

3°.52' - 2°.49' = 232' - 169'
= 63'
63' = 63 ÷ 60 = 1°.03'

Jawab : A

4.) 13 jam = 13 × 60 = 780'
780' + 14' = 794'

½ × 794 = 397'

397' = 397 ÷ 60 = 6°.37'

jawab : C


maaf, kalau salah
