I worked out the apparent mag of the supernova as 14.96...using the equation d=v/H, where d id the distance to the object, v is the recessional velocity (in Kms) and H is the Hubble constant (which I took as 71kms/mpc). I found the distance and then plugged the absolute mag for a supernova (around -18.5) and the distance into the distance modulus formula...m-M=5logD-5, m= apparent magintude, M=absolute magnitude and D= distance to object.
