the 900 km/hr vector is the hypotenuse and the 100km/hr vector is one of the legs of the right triangle. velocity is the other leg. v^2 + 100^2 = 900^2 v = sq root (900^2 - 100^2) v = 894 km/hr due east

draw a diagram.
find all north south velocities
find all east west velocities
do Pythagorean theorem.
sqrt(900sin45-100)^2+(900sin45)^2
turns out to be 832.3km/h
