Activity
In this activity, you will use Hubble's law, v= Hod, and the definition of velocity, = 4, to calculate the approximate age of
the universe, t. Consult the math review if you need help with scientific notation, exponents, or solving one-step
equations.
Part A
To find time, t, the age of the universe, you must first isolate the variablet. Rewrite the velocity equation = so that you
are solving for time.
