The difference between them is 3,600 meters.
4 km is ten times as long as 400 m.
4 lengths
400 km = 4*1014 nm
4 kilometer
1 km = 1000 metres and 1 metre = 100 cm so 1 km = 105 cm So 400 km = 4*107 cm.
No: 7km = 7000m
400 m =0.4 km
.4 km
To find the fraction of 1 km that 400 m represents, first convert 1 km to meters, which is 1000 m. Then, divide 400 m by 1000 m: ( \frac{400}{1000} = \frac{4}{10} = \frac{2}{5} ). Therefore, 400 m is ( \frac{2}{5} ) of 1 km.
Depends how big your pool is, doesn't it? A 25-yard pool would make you do 4 lengths (one-way across) per 100 yds, which is 16 lengths for 400 yds.
i dont know, but if you are driving at 100 km/hr it takes 4 hours :)
around 400 Km / 3-4 hours
14 tens is 140 4 hundreds is 400 The difference is 260.
