      after journeying for 5 hours, completing his trip in a total of 8 hours. If instead he had boosted his speed by 18 km/h after the initial 5 hours, he would have arrived at his destination 30 minutes earlier. Calculate the distance Abhinav covered during the portion of his trip with the increased speed.
