2) 20 mil a) 20 x 1,609 km = 32,18 km b) misal 1 inchi = 2,5 cm 1 mil = 1, 609 km = 1609 m = 160900 cm = 160900/2,5 = 64360 inchi 20 mil = 20 x 64360 inchi = 1287200 inchi c) 1 inchi = 1/12 kaki 20 mil = 1287200 x 1/12 = 107266,7 kaki
a) 20 x 1,609 km = 32,18 km
b) misal 1 inchi = 2,5 cm
1 mil = 1, 609 km = 1609 m = 160900 cm
= 160900/2,5 = 64360 inchi
20 mil = 20 x 64360 inchi
= 1287200 inchi
c) 1 inchi = 1/12 kaki
20 mil = 1287200 x 1/12
= 107266,7 kaki
3) 3. 10⁸ m/s = 3.10⁸.10³ mm/s
= 3.10¹¹ mm/s
4) 11, 3 gr/cm³ = 11,3 . 10⁻³ kg / (10⁻²)³ m³
= 11,3 . 10⁻³.10⁶ kg/m³
= 11,3 .10³ kg/m³
= 11300 kg/m³
5) misal 1 thn = 365 hari
1 hari = 24 jam
1 jam = 3600 detik
10⁶ tahun = 365 x 24 x 3600 x 10⁶ detik
= 315360 x 10⁸ detik
= 3,15 x 10¹³ detik
6) G = F . r² / M.m
= m.s/t² .r² / m²
= s.r² /t².m
= L.L² / T².M
= M⁻¹L³T⁻²
7) k = P.V
= F/A. V
= F/A. A.h
= F.t
= m.s/t². h
= M.L²T⁻²
