Answer:
36.1 km/h
Step-by-step explanation:
rate at which the distance is changing is given by relative velocity(vR)
Look at the diagram. THe diagram shows relative motion. From relative motion diagram, velocity vector diagram is drawn.
From velocity vector diagram, it can be seen that relative velocity or vR can be calculated using pythagoras theorem.
vR²= vA² + vB²
vR²= 30²+ 20²
vR= 36.1 km/h
