A boy started walking towards east at 10:00AM and took a right turn after walking for 10km.
Then he walked in the same direction for about 30minutes and then turned to his right and walked for 4km and stopped.
If the boy maintains a uniform speed of 30m/sec, in which direction would the shadow of the boy be falling at the end.?
30 mps = 108 kmph, total distance traveled is less than 10+ 54 (half an hour) +4 =68 so the time will be between 10:00 and 11:00 AM since the sun rises in the east, no matter how the boy travels, shadow will be towards west.
