Tolong dijawab no 17-20 ya pakai caranya
17. 3,25 km = 3250 m
Jln R. Suprapto = 15 hm
= 1500 m
Jln MT Haryono = 1025 m
Jln Sudirman = 3250 – (1500 +1025)
= 3250 – 2525
= 725 m (a)
18. 1,8 jam = 108 menit
Gaya dada = 25 menit
Gaya kupu-kupu = 1200 detik
= 20 menit
Gaya bebas = 108 – (25 + 20)
= 108 – 45
= 63 menit
19. 60/5 = 12 liter/menit (b)
20. 2 (13) + 2 (20) = 26 + 40
= 66 cm (b)
Maaf kalau ada yang salah
