It is equivalent to 6-27m after expanding the brackets
1km= 1000m 13km=13000m
13cm+13dm+13km+13mm
27m equals 0.027km
1 km = 1000m ⇒ to convert m to km, divide by 1000 ⇒ 27m = 0.027 km
15-20minutes
27m
2700cm, 27000mm
13km = 8.07783 miles.
A kilometer is a thousand meters, so 13000
512.2x10-15km or 5.122x10-13km
Well, if a rock is throws 27m into the air, it will probably reach the water faster than 27m because of gravity.
