as the first one takes 17 mins less for the same distance, in the previous part of the question we can observe that the difference in time is 10 min, and distance is 1 km, so for the remaining km second person would take 7 more min, thereby taking the speed of the second guy as 1/7 km/min, hence deducing that in 52 min at 1/7km/min he would cover 7.43 km, so the total distance between delhi and noida is 7.43+2= 9.43 km or 9.5.
