#v = H0 * r #

Explanation:

Hubble's law states that Every object in the observable universe is receding away from us at a speed proportional to it's distance. So, the greater the distance, the faster that object is traveling away from us. This can be given by,

#v = H@ * r #

Where,

#v# is the velocity.

#H@# is the Hubble's constant, 70 km #sec^-1# #megaparsec^-1#

This means that an object at a distance of 1 Megarparsec will have a speed of about 70 km/ sec.

#r# is the distance.
