Velocity of car wrt passenger on train = -30i + 40j km/h
|v| = √(30^2 + 40^2) = 50 km/h
It will appear going north west at a speed o 50km/h

As the given details, we can consider the a train is moving with a velocity of 30 km/hr due east and a car moving with velocity 40 km / hr due north.
The velocity of car is given as -30i + 40j km/h.
The next step is |v| = √(30^2 + 40^2) = 50 km/h.
Hence, it will actually appear going North West at a speed of 50km/h.
