Jawaban:

1. 15.500 dm = 1,55 km

= 155 dam

= 15,5 hm

2. 100 dam + 10 km = 10 hm + 100 hm

= 110 hm

3. 1 jam = 60 menit

1/2 jam = 30 menit

1 1/2 jam = 60 + 30 = 90 menit

4. 2 jam = 2 × 60 = 120 menit

1/4 jam = 15 menit

2 1/4 + 15 menit = 135 + 120

= 150 menit

5. 1,5 ÷ 1.000 / 1 ÷ 3.600 = 1,5 × 3.600 / 1 × 1.000

= 5.400 / 1.000

= 5,4 km/jam

6. 75 km/jam = 75 × 1.000 = 75.000 m/jam

7. Jarak ÷ waktu = 90 ÷ 3/4

= 90 × 4/3

= 120 km/jam

8. t = s/v = 60.000/50 = 1.200 menit

9. 60/60 × 45 = 45 km

10. 1/2 km = 0,5 km = 0,5 × 1.000 = 500 m

500 ÷ 100 = 5 menit
