Answer:
3km/h
Step-by-step explanation:
Let the person starting from P be A and the person starting from Q be B.
Rate at which A walks=4km/h
Distance covered in 6h=4*6=24km
Total distance=42km
Distance not covered=42-24=18km
So, distance covered by B=18km
Time taken =6h
Rate at which B walks=18/6=3km/h
