The hubble constant has the dimensions of


ANSWER

$${ time }^{ -1 }$$


SOLUTION
Hubble's law states that the red shift in light coming from distant galaxies is proportional to their distance from the earth.
$$v = Hd$$
where $$H$$ Hubble's constant.
$$\therefore$$ Dimension of $$H = \dfrac { Dimension\quad of\quad v }{ Dimension\quad of\quad d } $$
Dimension of  $$H= \dfrac { { \left[ LT \right]  }^{ -1 } }{ \left[ L \right]  } = \left[ { T }^{ -1 } \right] $$
