1 mila = 1,609344 km
6 mil = x
x= 1,609344 * 6 /1 = 9,656064
6 mil = 9,656064 km
6 mil ≈ 9,7 km
1 cal = 2,54
20 cali = x
x= 2,54 * 20 / 1 = 50,8
20 cali = 50,8 cm
1 stopa = 0,3048 metra
30 stóp = x
x=0,3048 * 30 / 1 = 9,14400 m
30 stóp = 9,14400 m
30 stóp ≈ 9,1 m
6mil=9,65kkm
(1mila=1,609344)
20cali=50,8cm
(1cal=2,54cm)
30stóp=9,144
(1stopa=0,3048m)
