Sri krishna took the chariot and started his journey from mathura to gokul by his chariot at the speed of 40 km/hr nad then the same distance he travelled on his foot at the speed of 10km/hr from gokul to brindaban . Then he returned from brindanban to mathura via gokul at the speed of 24 km/hr riding on the horse . The average speed of the whole trip is :

Answer»

20km/hr
25 km/hr
19.2 km/hr
18.5 km/hr

Solution :since the distance from mathura to gokul is same that of gokul to brindaban . So the AVERAGE speed from mathura to brindaban =`(2xx16xx24)/(40+10)`=16km/hr`
again since he RETURNED on the same PATH so the distance from mathura to brindaban is same in boththe DIRECTIONS . thus the REQUIRED average speed =19.2 km/hr.
