4 lengths
400 km = 4*1014 nm
4 kilometer
Oh, dude, you're hitting me with some intense math here. So, if we have a 4-meter ribbon and cut it into 20cm lengths, that means we're getting 20 pieces out of it. Each piece is 0.2 meters long because 20cm is 0.2 meters. Math is wild, man.
1 km = 1000 metres and 1 metre = 100 cm so 1 km = 105 cm So 400 km = 4*107 cm.
No: 7km = 7000m
.4 km
400 m =0.4 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.
around 400 Km / 3-4 hours
i dont know, but if you are driving at 100 km/hr it takes 4 hours :)
14 tens is 140 4 hundreds is 400 The difference is 260.
