If a galaxy has an apparent radial velocity of 1,214 km/s and the Hubble constant is 70 km/s/Mpc, how far away is the galaxy?

i think if it were me i whould divide 300 dide 15

step-by-step explanation:

the total distance traveled by the car is

30km + 49km = 79 km .

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
