Jawaban:
1. B
2. C
Penjelasan dengan langkah-langkah:
1. AB : BC = 2 : (6 - 2)
AB : BC = 2 : 4
AB : BC = 1 : 2
2. waktu = 6/2 × 12/24 × 60
= 3 × 1/2 × 60
= 180/2
= 90 menit
AB : BC = 2 ÷ ( 6 - 2 )
AB : BC = 2 ÷ 4
[tex]ab : bc = \frac{2}{4} \div \frac{2}{2} [/tex]
[tex]ab : bc = 1 : 2[/tex]
[tex] waktu [/tex]
[tex] \frac{6}{2} \times \frac{12}{24} [/tex]
[tex] 3 \times \frac{1}{2} \times 60[/tex]
[tex] 3 \times \frac{60}{2} [/tex]
[tex] 3 \times 30 [/tex]
[tex] 90 menit [/tex]
