Answer:
it's his family matter we should not interped
Step-by-step explanation:
Speed of first=s=200/4=50km/h
Speed of second=S=200/3.5=400/7km/h
Till 8 A.M. first one has already covered 50 x 2=100 Kms
So now both are 100 km apart
They are approaching each other
So relative speed=50+400/7=750/7 Km/h
Time=100/(750/7)=700/750=14/15 hours=14x60/15=56 minutes
So they will cross each other at 8.56A.M
