Answer:
Distance=11502dam
Time=3 hours
Speed =distance/ time= 11502/3=3834dam/hour
Distance covered=11502-3627=7875dam
Time taken =2 1/4 hours=9/4
Speed = distance/time
=7875/9/4=3500 dam/hour
He has to increase 3834-3500=334dam in one hour
So he has to increase speed in 3 hours = 3.34 km×3= 10.02 km/hour
So to reach in time he has to increase 10.02 km/ hour.
