Two parallel rail tracks run north-south...

Two parallel rail tracks run north-south. Train A moves north with a speed of 54 km `hr^-1` aned train B moves south with a speed of 90 km `hr^-1`. What is the (i) velocity of B with respect to A ? (ii) velocity of ground with respect to A? (iii) velocity of a monkey running on the roof of 18 `km//hr` with respect to train A as observed by a man standing on the ground.
