Assuming that the canoes were at rest when they were pushed apart, the total momentum in the system must be zero.  This means that the momentum of canoe 1 must have the same magnitude as the momentum of canoe 2, but in opposite directions.

p1 = -p2

m1v1 = -m2v2

m1v1/(-v2) = m2

m2 = 350kg(0.60m/s)/[-(-0.45m/s)]

mx = 470 kg (Rounded to 2 significant figures)
