hey mate here is your answer
so in time 30 min to distance is 6300-1800=4500m
t=30min=1800sec
so s=d/t
=4500/1800=2.5m/sec
now from 8:30 onwards
t=d/s
=1800/2.5=720sec=720/60min=12min
so he will reach at 08:42a.m.
hope it will help you

In 30min the distance = 6300-1800=4500m
Time 30min in 1800sec
so v/d
4500/1800= 2.5m/sec
now
t=d/v= 1800/2.5=720sec
t= 720/60
12min
He will reach at 8.45clock
