Answer:
Party start at 7’o clock
Total time spend by Bholu = 40 min (traveling) + 5 min (chatting) = 45 min
So Bholu has to reach Golu’s house within 15 min (1hour – 45 min)
The speed with which Bholu has to cover the second part of the journey is= 3/15 Km/min=12 Km/h
Average The average of Bholu’s in the entire journey is total distance divided by total the time taken is
