An iceberg breaks off from the Antarctic continent and floats due north at constant velocity/ It's latitude south decreases by 1 degree in 8 days. Taking the circumference of the earth to be 40 000km, calculate the speed of iceberg in ms^1.

Hint:
Circumference=40000km
radius, r
= 40000/(2π) km
= 40000/(2π)*1000 m
angular speed, ω
= 1 degree/8 days
= (π/180)rad. / (8*86400) sec.
terrestrial speed
= rω
I get less than a metre per second.
