19. [13 Points] AUFQMCDREQ 5.4.006. ASK YOUR TEACHER PRACTICE ANOTHER Astronomer Edwin Hubble postulated a relationship between the distance between Earth and the velocity at which a galaxy appears to be traveling away from Earth. The following table shows observations of seven galaxies. Distance is measured in megaparsecs (1 Mpc is approximately 3,260 lightyears), and velocity is measured in kilometers per second.

(Round your numerical answers to two decimal places.) p: (b) Using the equation from part (a), estimate the velocity (in kilometers per seoond) at which a galaxy 130 Mpc from Earth is traveling. (Round your answer to the nearest whole number.) |:| k
