I'll do it for you shall I 
1200/72 = 16.66666666666666666666666666667
15000/900 = 16.66666666666666666666666666667
The 16.6.....7 is Hubbles constant its just the simple matter of rearranging the formula.
to find the distance of Hydra just 60000/6.666666666666667= 3600
to find the velocity of Perseus just do 400x16.66666667= 6666.666666...7
if you need any further help just ask!  | Come on you should at least have given him something to work out rather than doing it for him  |

Out of curiosity Leifus do they teach the manner in which Einsten added what he later called a 'fudge factor' to his maths 'cos pre Hubble the universe was believed to be static?
