I have the question
Use the answer to question 1 to calculate the linear velocity of a point on the surface of the Earth (radius of Earth = $6.4 \times 10^6$ [m]).
So the answer for question 1 was $7.3 \times 10^{-5}$ [rads$^{-1}$].
Now using this is question 2 I know that the formula for linear velocity is $V = rw$.
So $V = 6.4 \times 10^6 m \times 7.3 \times 10^{-5} rads^{-1}$
Therefore V = 467.2 [radms$^{-1}$].
However, I do not know if the units for the final answer are correct.

Rad is essentially a dimensionless unit. So $\omega R$ has dimensions of velocity.
