1. A man can row 8 km/hr in still water. In a river running at 2 km/hr an hour, it takes him 40 minutes to row to a place and back, how far off is the place? Answer: 2.5 kms Solution:  u = 8 km/hr;  v = 2 km/hr Speed downstream = (u+v) = 10 km/hr;  Speed upstream = (u-v) = 6 km/hr Let x be the length of the river x/10 + x/6 = 40/60; x = 2.5 kms 2.  A man takes 3 hours 15 minutes to row a boat 13 kms downstream of a river and 1 hours 30 minutes to cover a distance of 4.5 kms upstream. Find the rate of current in km/hr.  Answer:  1/2 km/hr  Solution:   Rate downstream = 13/(13/4) = 4 km/hr, Rate upstream = 4.5/3/2 = 3 km/hr; Rate of   current = 1/2(4-3) = 1/2 km/hr 3.  Speed of a boat in standing water is 9 kmph and the speed of the stream is 1 kmph. A man rows to a place at a distance of 120 km and comes back to the starting point. The total time taken by him is: Answer: 27 hours Solution:  Speed upstream = 9-1 = 8 kmph; Speed downstream = 9+1 =10 kmph. Total time taken = (120/8 + 120/1
