I'm assuming you mean 11.07 seconds. (100 m / 11.07 s) * (1 km / 1000 m) * (0.62 mi / km) * (3600 s / 1 h) = 20.16 mi/h
299 792.458 km s-1.This is not an approximate figure - it is exactly right by definition.If there was a tiny error it will be corrected by adjusting the meter !
299792.458 km/s x 480 s ≈ 143,900,000 km
Twenty cm-s higher than a metre, altogether 120 cm, or 1200mm (or 0.12 km).
100 centimeters.
There are approximately 1.609 kilometres per mile, so divide 220 by 1.609, or approximately 136.73 mph.
To convert from m/s to km/s, divide by 1000. So, 20 m/s is equal to 0.02 km/s.
Between about 220 million and 250 million years.
1 km = 1000 meter 8 km = 8*1000 = 8000 m
