Description : A man rows 750m in 775 seconds against the stream and returns in 7 1/2 minutes. What is rowing speed in still water ? A.4.7km/hr B. 4km/hr C.3.5km/hr D.6km/hr
Last Answer : Answer-A Basic Formula: i) Speed in still water = ½ (a+b) kmph where a' is speed downstream and b' is speed upstream ii) a km / hr = a x 5/18 m /s iii) a m/sec = a x 18/5 km/hr Explanation: Speed upstream b' ... (750/450 + 750/675 ) x 18/5 km/hr = ½ (5/3 + 30/31) x 18/5 km/hr = 4.7 km/hr

Last Answer : ANSWER : A Explanation: Rate upstream = (1500 / 1350) m/s = (150/135) m/s = 10/9 m/s Rate downstream = (1500 / 900)m/s = (15/9)m/s = 5/3 m/s Rate in still water = ½ [ a+ b] = ½[10 / 9 + 5 /3 ... +15 / 9] = ½[25/9] = 25/18 m/s = (25/18) * (18/5)km/hr speed in still water = 5km/hr
