Best Answer: Walking a mile a day would improve your general cardiovascular health. It would give you more stamina and endurance. It would help your resistance to disease. It would build muscle mass in your legs.
A summary of these methods: 1  Cepheid variable stars and their cousins the RR Lyrae stars are the primary distance indicators in the galaxy and the local group. 2  They pulsate radially (basically at the sound speed in the envelope of the star) with a period inversely proportional to the square root of the density.
(1)] where v is the galaxy's velocity (in km/sec), d is the distance to the galaxy (in megaparsecs; 1 Mpc = 1 million parsecs), and Ho is the proportionality constant, called The Hubble Constant. Hubble's Law states that a galaxy moving away from us twice as fast as another galaxy is twice as far away.
